Question

G(x) = −2x + 4
f (x) = −4x − 12/5
Are they inverses or not

Answer 1

• No, they are not inverses

Explanation:

• g(x) = −2x + 4
• f (x) = −4x − 12/5

Let's get inverse of g(x) and compare it with f(x):

• g(x)= -2x + 4
• x = - 2g'(x) + 4
• 2g'(x) = - x + 4
• g'(x) = -1/2x + 2

g'(x) and f(x) are different so the answer is No
