Question

If f(x) = 2x2 + 3x and g(x) = x – 2, what is (f + g)(2)?

A. 16
B. 14
C. 12
D. 10
D. 8

Answer 1

to find (f + g)(x) just add the 2 functions

the plug in x = 2

Answer 2

* then

Answer 3

How do you add the two functions. Sorry I've been away from school and I forgot how to do a lot of things.

Answer 4

Now you could have done f(2) + g(2) separately, which is: [2(2)2 + 3(2)] + [2 - 2] = 14 - 0 = 14

Answer 5

So is that the answer?

Answer 6

Now replace x by 2, and get the answer", so that's 2(2)2 + 4(2) - 2 = 14
