Question

F(x) = x2. Find the inverse of f(x).

Answer 1

Your answer would be C f(x)^-1=x+2
There are a couple steps to finding the inverse of a function,
1. Re write as a linear equation
2. Swap x and y variables
3. Solve for y
4. Re write in inverse notation

Hope this helped!

Answer 2

option C

Explanation:

f (x) = x - 2

y = x - 2

x = y -2

y - 2 = x

y = x + 2

-1

f (x) = x + 2
