f (x) = 2x + 1. g (x) = x^2 - 7. We will plug our equations for f (x) and g (x) into f (x) + g (x) as shown: (f+g) (x) = 2x + 1 + x^2 - 7. Now we will combine like terms (which is only the -7 and 1) (f+g) (x) = 2x + x^2 -6. Let's put it in order and get our answer! (f+g) (x) = x^2 + 2x -6. Upvote • 0 Downvote.

WebGiven f (x) = 3x + 2 and g(x) = 4 − 5x, find (f + g) (x), (f − g) (x), (f × g) (x), and (f / g) (x). To find the answers, all I have to do is apply the operations (plus, minus, times, and divide) that they tell me to, in the order that they tell me to. ( f + g ) ( x) = f ( x) + g ( x) = [3 x + 2] + [4 − 5 x] = 3 x + 2 + 4 − 5 x = 3 x − 5 x + 2 + 4
