Question

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

Answer 1

The first step is applying -3 to the two equations so. 2*-3= -6 so F(X)=-6+5 and G(x)= -3-7 now combine like terms to get the equation of f(g(x)= (-6-3 )or -9+(5-7) or -2 so f(g(x)=-9-2. Finally that means f(g(x)=-11 I believe?
