Question

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

Answer 1

B)

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
`-(√(x)-7)/(8),\:-(-√(x)-7)/(8)` and is a function.
