i need help answering this question as soon as possible. i don’t understand it

Answer 1

Answer:

B)

Step-by-step explanation:

Given f(x) = ( 7 - 8x )²

let f(x) be y,

y =  ( 7 - 8x )²  .............to find inverse we have to make x the subject.

±√y = 7 - 8x

-8x = √y  - 7

x = (±√y  - 7 ) / -8

Then,

Inverse of ( 7 - 8x )² is  $-\frac{\sqrt{x}-7}{8},\:-\frac{-\sqrt{x}-7}{8}$ and is a  function.
