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

katen-ka-za [31]

Answer:

No, they are not inverses

Step-by-step 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
