Will mark brainliest. i have attached the problem, and the answers are as follows: a ) 2x - h - 4 b) 2x - 3h - 4 c) 4x + 2h - 3 d ) 4x + h - 3

f(x+h)-f(x) / h

f(x) = 2x^2-3x-4

Replace X with (x+h):

2(x+h)^2 - 3(x+h) -4

Simplify:

2x^2 + 4hx +2h^2 -3x -3h -4

Now you have:

(2x^2 + 4hx +2h^2 -3x -3h -4 - 2x^2-3x-4) / h

Simplify to get 4x +2h-3

The answer is C.
