Question

Given that f(x) = 2x + 5 and g(x) = x − 7, solve for f(g(x)) when x = −3.

Answer 1

this means that you have to plug in the g(x) function into the f(x) function
f(g(x))=2(x-7)+5
now simplify
f(g(x))=2x-14+5
f(g(x))=2x-9
now plug in -3 for x
f(g(-3))=2(-3)-9
simplify
f(g(-3))=-6-9
f(g(-3))=-15
