6. [15 points] Suppose quot;)=4×3 -4x3h+11x +3h2 -14h. (Note: the algebra to find the

h

difference quotient was already performed for you. You have not been given the f-function.) Use this

result to find the following:

(a) [5 pts]

f (6) -f(1)

6-1

f (6)-f(1)

6-1

(b) [5 pts] the instantaneous rate of change at x = 3

Rate =

(c) [5 pts] the overall rate of change at x = 4
