If f(x)= x/2 -2 and g(x) = 2x2 +x-3, find (f +g)(x).
Molodets [167]

Answer:

B

Step-by-step explanation:

(f+g)(x) means add f(x) and g(x) together:

(x/2)-2 + 2x^2 +x -3

collect all the like terms:

2x^2

(x/2) + x = 3/2x (explanation below)

-2 -3 = -5

x/2 + x can be turned to 1x/2 + 2/2x (2/2 = 1, so when you simplify it to 1x, it is still x)
