Question

F(x) = 3x – 2 and g(x) = x2 + 1, find (f + g)(x)

Answer 1

Option A:  x^2 +3x-1 is the correct answer

Step-by-step explanation:

Given functions are:

$f(x) = x-2\\g(x) = x^2+1$

We have to find (f+g)(x), which is the addition of two given functions

So,

$(f+g)(x) = f(x) +g(x)\\= 3x-2 + (x^2+1)\\= 3x-2+x^2+1\\= x^2+3x-2+1\\=x^2+3x-1$

Hence,

Option A:  x^2 +3x-1 is the correct answer
