Question

f(x) = 2x + 6, g(x) = 4x^2

Find (f + g)(x).

8x^3 + 24x

(2x+6)/(4x^2)

4x^2 + 2x + 6

-4x^2 + 2x + 6

Answer 1

(f + g)(x)

is the same as

f(x)+g(x)

Answer 2

yes ^^^

Answer 3

just add the two together...

Answer 4

So simply replace f(x) with 2x+6 and replace g(x) with 4x^2 to go from

f(x)+g(x)

to

(2x+6)+(4x^2)

Answer 5

Combine like terms if you can and rearrange the terms.

Answer 6

4x^2+2x+6?

Answer 7

that's it

Answer 8

thank you very much :D

Answer 9

In this case, there are no like terms, so you just rearrange in the proper order.
