What is the graph of an exponential decay function would have a curve upward along the x-axis towards negative infinity?
Your question seems very confused. The normal convention of the Cartesian coordinate system would place negative numbers below the x axis, so that any curve approaching negative infinity would curve downward, not upward.
How determine the area of curve under the x-axis?
Integrate the function for the curve, as normal, but the change the sign of the result. Be very careful that the curve is always on the same side of the x-axis between the limits of integration. If necessary, partition the integral. For example, to find the area between the x-axis and sin(x) between x=0 and x=3*pi, you will need Integral of sin(x) between 0 and pi, -[integral of sin(x) between pi and 2*pi] - this is where the curve is below the x-axis. +integral of sin(x) between 2*pi and 3*pi.
How do you find the area between a given curve and x-axis?
Take the definite integral (and your bounds should be the two places where the curve crosses the x-axis).
Where do you find the solutions to a quadratic equation on a graph?
The solutions to a quadratic equation on a graph are the two points that cross the x-axis. NB A graphed quadratic equ'n produces a parabolic curve. If the curve crosses the x-axis in two different points it has two solution. If the quadratic curve just touches the x-axis , there is only ONE solution. It the quadratic curve does NOT touch the x-axis , then there are NO solutions. NNB In a quadratic equation, if the 'x^(2)' value is positive, then it produces a 'bowl' shaped curve. Conversely, if the 'x^(2)' value is negative, then it produces a 'umbrella' shaped curve.
Do the Asymptotic means that the normal curve gets closer and closer to the X-axis but never actually touches it?
yes, an asymptote is a curve that gets closer but never touches the x axis.
Why two tail of normal distribution do not touch the horizontal axis?
The domain of the Normal distribution is the whole of the real line. As a result the horizontal axis is asymptotic to the Normal distribution curve. The curve gets closer and closer to the axis but never, ever reaches it.
Does a normal curve ever intersect the x axis?
No
How do you find the area enclosed by the curve y equals 7x-x2-10 and the x-axis?
The area under a curve (between it and the x-axis) is found by integrating the curve: area = ∫ y dx The area enclosed between the curve and the x-axis is bounded by where the curve meets the x-axis. 7x - x² - 10 = -(x - 2)(x - 5) = 0 → The curve meets the x-axis at x = 2 and x = 5 The area between the limits is the difference between the value of the the integral at the limits. → A = ∫ y dx = ∫ 7x - x² - 10 dx = (7/2)x² - (1/3)x³ - 10x + c → A = ((7/2)×5² - (1/3)×5³ - 10×5 + c) - ((7/2)×2² - (1/3)×2³ - 10×2 + c) = 4.5
Distinguish between demand curve and engel curve?
The difference is the Y- axis. In the case of the Demand curve the Y - axis is the retail price of the good. On the Engel's curve the Y -axis is the amount of income over a set period of time.
Which solid figure has only one face?
cone +++ A sphere or other full solid of revolution generated about either axis where the curve meets that axis in 2 places, and those intercepts are the solid's poles. (A cone has 2 faces)

What are the characteristics of a normal distribution curve?
Characteristics of a Normal Distribution1) Continuous Random Variable.2) Mound or Bell-shaped curve.3) The normal curve extends indefinitely in both directions, approaching, but never touching, the horizontal axis as it does so.4) Unimodal5) Mean = Median = Mode6) Symmetrical with respect to the meanThat is, 50% of the area (data) under the curve lies to the left ofthe mean and 50% of the area (data) under the curve liesto the right of the mean.7) (a) 68% of the area (data) under the curve is within onestandard deviation of the mean(b) 95% of the area (data) under the curve is within twostandard deviations of the mean(c) 99.7% of the area (data) under the curve is within threestandard deviations of the mean8) The total area under the normal curve is equal to 1.
What is typically displayed on the x-axis of a solubility curve?
The x-axis of a solubility curve typically displays temperature in degrees Celsius.

What is the point where the axis meets the y axis?
the origin and it has the coordinates of (0,0)
