Question

How to solve this problem

Answer 1

you need to plug your g(x) into the function f(x)

f(g(x))= 9(-x+3)-2, then you just distribute the 9 to set in the parentheses

f(g(x))= -9x+27-2, then finally you combine your like terms to get

f(g(x))= -9x+25

Answer 2

F(x)=9X-2

g(x)=-x+3

in f(x), re[place x with g(x) to obtain f(g)(x))

f(g(x)=9g(x0-2

=9(-x+3)-2

-9x+27-2

F(g(x))=-9x+25
