Question

For f(x)=2x+1 and g(x)=x^2-7, find (f+g)(x).

Answer 1

put a plus sign between them

Answer 2

f(x) + g(x)
would be the same as (2x+1) + (x^2-7)

what do you get after adding them ?

Answer 3

i get x^2+2x-6

Answer 4

yes

Answer 5

do you want to graph it or just need to find the expression for (f+g)(x) ?

Answer 6

x^2+2x-6 is one of the answers to pick from so I guess I just needed to find the expression for (f+g)(x) thank you!
