-n/3=4
-n/3 x 3=4 x 3
-n=12
-n/-1=12/-1
n=-12
Answer:
Step-by-step explanation:
Given is a function



Average slope of this function is change of f(x) in (-2,6)/change of x in (-2,6)
= 
By mean value theorem there exists a c such that f'(c) = -18
i.e. 
Using quadratic formula
x = 2.61, -1.277
Out of these only 2.61 lies in the given interval
c = 2.61
