Question

If f(x)=3x^2-1 and g(x)=x+2, find (f+g)(x)

Answer 1

Answer:

Step-by-step explanation:

X^2+3x-1 apex

Answer 2

Answer:
(f+g)(x) = 3x^2 + x + 1

Explanation:
We are given that:
f(x) = 3x^2 - 1
g(x) = x + 2
To find (f+g)(x), all we have to do is add the above to functions as follows:
(f+g)(x) = f(x) + g(x)
= 3x^2 - 1 + x + 2
= 3x^2 + x + 1

Hope this helps :)
