It does if arranged properly.
y = F(x) is definition of y as a function of x. Put the equation in this form and it will be a function of x.
y = F(x) = 25 - x^2

x^2 + y = 25
or y = 25 - x^2,
here y is a function of x.

Solve for y:
y = -x^2 + 25
Is this a function?
Yes, because it passes the vertical line test.

This is a simple math homework. Put some neurons into it.
