Answer:

14

Step-by-step explanation:

(f + g)(x) = f(x) + g(x) = 2x² + 3x + x - 2 = 2x² + 4x - 2

To evaluate (f + g)(2) substitute x = 2 into (f + g)(x)

(f + g)(2) = 2(2)² + 4(2) - 2 = 8 + 8 - 2 = 14

Answer:

14

Step-by-step explanation:

First find an algebraic formula for (f + g)(x).  To do this, combine like terms from f and g:  (f + g)(x) = 2x^2 + 4x -2

Next, substitute 2 for x:  (f + g)(2) = 2(2)^2 + 4(2) - 2 = 8 + 8 - 2 = 14
