Question

Can someone please help me?



Given: f(x) = x² and g(x) = 2x + 1, find f[g(x)].

Answer 1

2x^2 + 1

4x^2 + 1

4x^2 + 4x + 1

Answer 2

easy find g(x) first, then plug in that answer into the f(x) equation-that probably makes no sense though.

I need an x value or do you just want the combined equation?

Answer 3

If it is just the combined equation it would be this..

\[x ^{2}(2x+1)\]

Answer 4

Distributive property...

Answer 5

f[g(x)] = f*x*g = g(x²) = x²(2x + 1). Correct me if I'm wrong please.

Answer 6

It's multiple choice and the choices are

2x^2 + 1

4x^2 + 1

4x^2 + 4x + 1

Answer 7

4x^2 + 1. I'm pretty sure. Correct me if I'm wrong.

Answer 8

Well if x=2 I would plug it into g(x) an get 2(2)+1=5
Now plug 5 into f(x)
5^2=25
