Question

math problem

Answer 1

This is asking for
f(g(x))

Answer 2

Which means in each x in f(x), change it to 2x+1

Answer 3

2x+1^2-2 2x+1+3?

Answer 4

\[(2x+1)^2 -2(2x+1) +3\]

Answer 5

Can you simplify that?
remember that
\[(a+b)^2 =a^2 +2ab+b^2\]
and
\[a(b+c) = ab+ac\]

Answer 6

one sec, let me add brackets

Answer 7

4x^2+4x+1

Answer 8

\[4x^2 + 4x-1 -2(2x+1)+3\]

Answer 9

And can you simplify
-2(2x+1)

Answer 10

im not sure

Answer 11

a(b+c) = ab+ac
the distribution property

Answer 12

-4x-2?

Answer 13

Yep
So now we have
\[4x^2 + 4x-1-4x-2+3\]
simplify, combine like terms

Answer 14

wai waittttt it's +1

Answer 15

4x^2+x+-1+3

Answer 16
