Consider the function f(x) = x² – 3x – 4 and complete parts (a) through (c). (a) find f(a+h); f(a+h)-f(a) (b) find (c) find the instantaneous rate of change of f when a = 7. (a) f(a+h) = (simplify your answer. do not factor.)

(a)

(b)

(c)

Step-by-step explanation:

(a)

Simply evaluate (a+h) in the function:

(b)

Evaluate (a) in the function:

Using the previous answers lets calculate f(a+h)-f(a)

(c) To find the rate of change of f(a+1) when a=7 we need to calculate its derivate at that point:

answer: apothems is your answer

step-by-step explanation: hope u get it right

the correct answer would be:
