G(x) = −2x + 4<br> f (x) = −4x − 12/5 <br> 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

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

  • 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
