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.

Weight = 180/2.2 = 81.81 kg
Duration = 8 minutes

Substituting;
Calories used = 0.22*81.81*8 = 144 calories
