If f(x) = 2x2 + 3x and g(x) = x – 2, what is (f + g)(2)?
goblinko [34]
For this case we have the following functions:
 f(x) = 2x^2 + 3x

g(x) = x - 2
 The first thing we must do is calculate the sum of functions or equivalently:
 (f + g)(x) = f(x) + g(x)

 We have then:
 (f + g)(x) = (2x^2 + 3x) + (x - 2)

 To complete the sum, we must add the terms whose exponents are equal.
 We have then:
 (f + g)(x) = 2x^2 + (3x + x) - 2

(f + g)(x) = 2x^2 + 4x - 2
 Then, we evaluate the function for x = 2:
 (f + g)(2) = 2(2)^2 + 4(2) - 2

 Rewriting we have:
 (f + g)(2) = 2(4) + 4(2) - 2

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

(f + g)(2) = 14
 Answer:
 
(f + g)(2) = 14
