If a function is negative at a test number it will reach zero before it reaches an asymptote?
Not necessarily. f(x) = -1-x2 is negative for any test value of x, it is asymptotically negative infinity, but it is NEVER zero.
What point is infinity?
Infinity, by definition, is not a point. Infinite means unending, so it cannot be located at a point. The moment at which a function reaches infinity is when that function ceases to be bounded.
When the value of the slope gets smaller the graph of a line gets what?
When the slope of a line reaches zero it then will be parallel to the x or y axes depending if its a positive or a negative slope.
When the absolute value of the slope gets smaller the graph of a line gets?
When the slope of a line reaches zero it then will be parallel to the x or y axes depending if its a positive or a negative slope.
What term is used to describe a represntation of a thing or system and can be used as a way to test hypotheses?
A graph is a representation of a thing/system, and can be used to test a hypothesis. For example, if you have a graph of a trend you can find the function of that trend. Then, you can plug in values the graph defines--say, at 2 the graph reaches 5--and if the function works, you know you have modeled the phenomenon correctly. This function testing can work to test a hypothesis, especially in finding trends.
A line is an for a function if the graph of the function gets closer and closer to touching the line but never reaches it?
asymptote

Sketch a Tangent Functions?
A tangent function is a trigonometric function that describes the ratio of the side opposite a given angle in a right triangle to the side adjacent to that angle. In other words, it describes the slope of a line tangent to a point on a unit circle. The graph of a tangent function is a periodic wave that oscillates between positive and negative values. To sketch a tangent function, we can start by plotting points on a coordinate plane. The x-axis represents the angle in radians, and the y-axis represents the value of the tangent function. The period of the function is 2π radians, so we can plot points every 2π units on the x-axis. The graph of the tangent function is asymptotic to the x-axis. It oscillates between positive and negative values, crossing the x-axis at π/2 and 3π/2 radians. The graph reaches its maximum value of 1 at π/4 and 7π/4 radians, and its minimum value of -1 at 3π/4 and 5π/4 radians. In summary, the graph of the tangent function is a wave that oscillates between positive and negative values, crossing the x-axis at π/2 and 3π/2 radians, with a period of 2π radians.
What are the different trigonometric formulae?
In a right angled triangle with sides Adjacent (the angle is between this side and the hypotenuse), Opposite (this side is the side opposite the angle) and Hypotenuse (the side opposite the right angle).The six commonly used trigonometric ratios are:sine = opposite / hypotenusecosine = adjacent / hypotenusetangent = opposite / adjacent = sine / cosinecotangent = 1/tangent = adjacent / opposite = cosine / sinesecant = 1/cosine = hypotenuse / adjacentcosecant = 1/sine = hypotenuse / oppositeThere are various mnemonics to remember the first three of these ratios. Two such mnemonics which use the initial letters are:1: A nonsense word:SOHCAHTOA (pronounced sock-a-toe-ah or soh-ka-toe-ah)S = O/HC = A/HT = O/A2: A little rhyme:Two Old ArabsSoft Of HeartCoshed Andy HatchettT = O/AS = O/HC = A/HThe trigonometric functions are periodic:Sine (sin):Starts at 0° with a value of 0. It increases until it reaches 1 at 90°; then it decreases, reaching 0 again at 180° and continues onto -1 at 270°. Then it increases again, reaching 0 at 360° where it starts to repeat. Cosine (cos):Starts at 0° with a value of 1. It decreases, reaching 0 at 90° and continues onto -1 at 180°. Then it increases, reaching 0 at 270° and continues onto 1 at 360° where it starts to repeat. Tangent (tan):Starts at 0° with a value of 1. It increases towards an asymptote at 90°; it continues increasing, but from the negative side until it reaches 0 at 180° where it starts to repeat. Cosecant (csc = 1/sin):Starts with an asymptote at 0° and decreases from the positive side until it reaches 1 at 90°; where it then increases towards another asymptote at 180°; then it continues increasing from the negative side until it reaches -1 at 270° before decreasing again towards the asymptote at 360° where it starts to repeat. Secant (sec = 1/cos):Starts at 1 and increases towards an asymptote at 90°; it then increases from the negative side until it reaches -1 at 180° before decreasing again towards another asymptote at 270°. The it decreases fro the positive side until it reaches 1 at 360° and starts to repeat. Cotangent (cot = 1/tan):Starts with an asymptote at 0° and decreases towards 0 at 90°; it then continues to decrease towards another asymptote at 180° where it starts to repeat. As a result of this periodic nature, they have specific signs in the different quadrants of the cartesian plane:Sine: positive: I, II; negative: III, IVCosine: positive: I, IV; negative: II, IIITangent: positive: I, III; negative: II, IVCosecant: positive: I, II; negative: III, IVSecant: positive: I, IV; negative: II, IIICotangent: positive: I, III; negative: II, IVIf the angle is measured in radians, then the slopes of the trigonometric functions can be found by differentiating the functions:d/dx sin x = cos xd/dx cos x = -sin xd/dx tan x = sec² xd/dx csc x = -csc x cot xd/dx sec x = sec x tan xd/dx cot x = -csc² x
Can an A positive parent and a B positive parent have an O positive child?
Yes, with a percentage reaches only to 25%.
What is verical in volleyball?
Your vertical---if that's what you meant---is the difference between your standing hand touch and how high your hand reaches when doing an approach..subtract those two heights and that would be your vertical
What is the function of a diaphragm in a camera?
It controls the amount of light that reaches the film.
What is charge of lightning?
the charge of a lightning is positive and negative. The positive is on the top of a lightning cloud and the negative is surrounded on the bottom. As it flashes down it is a negative. However, the ground is a positive charge so as it reaches down, it turns into a positive charge. I hope this will answer you question
When a nerve impulse reaches the end of a motor neuron?
It fulfills its prime function - it turns that muscle ON - for a duration.
What point is infinity?
Infinity, by definition, is not a point. Infinite means unending, so it cannot be located at a point. The moment at which a function reaches infinity is when that function ceases to be bounded.
In projectile motion Why is the vertical component of velocity zero at the highest point of the trajectory?
Just before it reaches the highest point, the vertical component of velocity is upward.Just after it passes the highest point, the vertical component of velocity is downward.There's no way you can change from an upward velocity to a downward velocity smoothlywithout velocity being zero at some instant. A.True.
