best answer will be chosen!-If f(x) = -√x, and g(x) is the inverse of f, then the range of f is the domain of g.The range of f(x) = y = -√x is all real values of y ≤ 0, so the domain of g is all real y ≤ 0.......
domain of g?

a) y is not equal to 0
b) all rational numbers
c) all real numbers
d) y is greater than or equal to 0
e) y is less than or equal to 0

please show work. best answer will be chosen!

If f(x) = -√x, and g(x) is the inverse of f, then the range of f is the domain of g.

The range of f(x) = y = -√x is all real values of y ≤ 0, so the domain of g is all real y ≤ 0. (E)
