Question

Let f(x) = 3x+2 and g(x) = x^2

Part 1 Find f(g(x))
Part 2 Find g(f(x)) Let f(x) = 3x+2 and g(x) = x^2

Part 1 Find f(g(x))
Part 2 Find g(f(x)) @Mathematics

Answer 1

Is part 1: 3x^2 + 2
Part 2: 6x^2 + 12x + 4?

Answer 2

f(g(x)) means substitute the full function of g(x) for wherever there is x in f(x). Same with g(f(x)).

Answer 3

For example:
f(gx)) = 3 * (x^2) + 2

Answer 4

So is my answer right?

Answer 5

Yes!!
