Question

QF Q6.) Find the function for d.

Answer 1

We are looking for g(f(1)) which means that we need to find the value of f(1) and plug it into g(x) as x.

f(1) = 2(1) - 4

f(1) = -2

Now plug -2 into g(x) as x:

g(-2) = 4(-2)^2 - 3

g(-2) = 4(4) - 3

g(-2) = 16 - 3

g(-2) = 13

The answer is 13.

Answer 2

(g₀f)(1)=g(f(1))

=g(2(1)-4)

=g(-2)

=4(-2)^2-3

=16-3

=13
