Question

If f(x) = 4x and g(x) = 2x – 1, what is g(f(–2))?

Answer 1

The answer is negative seven teen

Answer 2

Answer is -17

Explanation:

Given that

`f(x) =4x\\g(x)=2x-1`

we have to find when x=-2 the composiiton of function g*f

First find out

`f(-2) = 4(-2) =-8`

Hence

`g{f(-2)} \\= g(-8) \\= 2(-8)-1\\=-17`
