Question

Hey, hot question real quick. I am doing Functions in Algebra and I kinda need help. So the function I have is **g(x)=x^2-9** and I have to evaluate **g^-1(x)**, but my question is how does the exponent go in front of the numbers? What does that mean? I know what to do with negative exponents but what do I do when they are in front of the numbers? How would I even write this?

Answer 1

g^-1 means "g inverse"
Clearly you have not studied the material.

For example, if
f(x) = 2x+5
g(x) = f^-1(x) = (x-5)/2
since
f(g(x)) = g(f(x)) = x
