Answer:

Correct option is:

A. (f + g)(x) = x² – x – 3

Step-by-step explanation:

We are given:

f(x) = 2x – 1 and g(x) = x² – 3x – 2

We have to find (f+g)(x)

(f+g)(x)=f(x)+g(x)

          = 2x -1 + x² - 3x - 2

          = x² +x(2-3) -1-2

          = x² -x -3

Hence, Correct option is:

A. (f + g)(x) = x² – x – 3
