Question

Perform the requested operation or operations.

f(x) = 4x + 9, g(x) = 4x2

Find (f + g)(x).

Answer 1

(f+g)(x) means f(x) + g(x)

Answer 2

so you just need to add the two functions and combine like terms (if there are any)

Answer 3

4x + 9 + 4x2 @jim_thompson5910

Answer 4

Yes but it's usually best to write it in order, highest powers first, to lowest.

Answer 5

so as agent0smith is saying, you would have \[\Large 4x^2 + 4x + 9\]

Answer 6

there are no like terms here, so you just leave the terms as they are
