Question

F(x)=x^2. What is g(x)?

Answer 1

g(x) = √x

Explanation:

g(x) = √x

Without any more information, it can be assumed g(x) is the inverse of f(x).

To find the inverse of a function, switch the x and y variables, then isolate y to find the equation.

f(x)=x^2 <= the f(x) is the same as y

y = x^2

x = y²

y = √x
