Answer:

Yes

Step-by-step explanation:

The function f(x) = x^2 - 1 is a quadratic due to its degree of 2. Its graph is a parabola or u-shaped graph which passes the vertical line test. This means it assigns each input a distinct output. Inputs do not repeat with different outputs. This is a function.

To find (f+g)(x), add the equations and simplify by combining like terms.

(x/2)-2+2x^2+x-3
2x^2+ (x/2) +x -5
2x^2 + (1/2)x+x -5
2x^2+ (3/2)x -5

Final answer: C

Remember that (x/2) is the same as (1/2)x. They both represent half of x.
