Question

If f(x) = 4x + 1 and g(x) = 3x + 2, what is f(g(x)) ?

Answer 1

f(g(x)) means you take the equation you have for g(x) ...and you plug it into f(x) everywhere you see an 'x'

so g(x) = 3x + 2

and f(x) = 4x + 1

so after replacing the 'x' with g(x) we have

f(g(x)) = 4(3x + 2) + 1

Can you take it from there?

Answer 2

i can try

Answer 3

substitute g(x)in f(x)........ .
