Question

Asked Aug 8, 2019

Step 1

(a)

It is given that the function* f*(*x*) = √(*x – *7).

Obtain the inverse of the function as follows.

Substitute *y* for *f*(*x*) in *f*(*x*) = √(*x – *7).

*y* = √(*x – *7)

Interchange *x* and *y*.

*x* = √ (*y – *7)

Take square on both sides,

*x*^{2} = (*y – *7)

Step 2

Solve the equation to obtain *y*.

Step 3
