Question

Given the function: g(x)=-1/2x + 3 What is the inverse function of g(x)?

Answer 1

Explanation:

Step 1 : Set g(x) = y

y = -1/2 x + 3

Step 2 : Make x the subject

y - 3 = -1/2x

1/2x = 3 - y

x = 2(3 - y)

x = 6 - 2y

Step 3 : Replace y by x and equat3 it to g^(-1)(x)

g^(-1)(x) = 6 - 2y
