Question

f(x) = -12x + 1
g(x) = 6x ^2 + 5x - 17
Find f(g(-8))

Answer 1

First substitute in G(x) x with 8 then the result substitute instead of x in the function F(x) .

Answer 2

\( \color{Black}{\Rightarrow f(6x^2 + 5x - 17) }\)

\( \color{Black}{\Rightarrow-12(6x^2 + 5x - 17) + 1 }\)

Simplify and operate on like the term(s).

Answer 3

@ParthKohli : Its G(-8) not G(X)

Answer 4

Whatever you will get, you will have to replace x with -8.
