Question

Which of the following equations defines y as a function of x?

Answer 1

Explanation:

the answer would be D

we can rewrite the function as F(y) = y^2. notice that this function is written as F(y) rather than F(x). if this were a function of y we would write it as F(x)= squareroot(x)

the difference between a function of x and a function of Y is that in a Function of x the x value will be isolated and in a function of y the y value will be isolated.
