Is y equals negative 4 a function?
yes
When you graph Y equals negative one would it be a function?
Yes and it will be a straight line intercepting y at -1 and parallel to the x axis
If y equals one half and x equals negative fourteen what is y?
One half!
Is y equals x-3 a function?
y = x - 3 is a linear function where for each x-value we find one and only one y-value.
Does the equation define y as a function of x x equals y squared?
It depends on the domain of y. If that is restricted to non-negative values, then the answer is yes. But if y is allowed to be negative, then the answer is no because then there are two values of y for each non-zero value of x.

What is the answer to y equals negative one half plus 2?
y = 1.5
The function y equals sin θ is not a function beacause sin 30 equals sin 150?
Y=sin X is a function because for each value of X, there is exactly one Y value.
Is the cosine function an odd function?
No. Cosine, along with sec, is an even function. The odd functions are sin, tan, csc, and cot. The reason for this is because is you take the opposite of the y-value for the cosine function, the overall value of the function is not affected.Take, for example, cos(60 degrees), which equals POSITIVE 1/2.If you flip it over the x-axis, making the y's negative, it becomes cos(-60 degrees), or cos(300 degrees). This equals POSITIVE 1/2.Now let's look at an odd function. For example, sin(30 degrees) equals POSITIVE 1/2. Now take the opposite of this.sin(-30 degrees), or sin(330 degrees), equals NEGATIVE 1/2. This is because it is found in the fourth quadrant, where the y's are negative. Sine of theta, by definition, is y divided by r. If y is negative, sine is negative.
Is y equals x-3 a function?
y = x - 3 is a linear function where for each x-value we find one and only one y-value.
Is y equals x4 an exponetial function?
If the question is, Is y = x4 an exponential function ? then the answer is no.An exponential function is one where the variable appears as an exponent.So, y = 4x is an exponential function.

It depends on the domain of y. If that is restricted to non-negative values, then the answer is yes. But if y is allowed to be negative, then the answer is no because then there are two values of y for each non-zero value of x.
Relation is a function y equals -8?
determine whether each relation is a function y equals -8
What is the axis of symmetry for the function - y equals x squared plus 2x plus 1?
y=x2+2x+1 -b -2 2a= 2= -1 = axis of symmetry is negative one.
X minus 4 y equals negative 7?
One can say that X+7 equals 4Y but we can not get an answer for X or an answer for Y without knowing one of them first.
