(1 point) Consider the function f(x)=−x3+2x2+2x+1 Find the average slope of this function on the interval (−2,6). equation edito

Whitepunk [10]

Answer:

Step-by-step explanation:

Given is a function

$f(x)=-x^3+2x^2+2x+1$

$f(6) = -6^3+2(6^2)+2(6)+1\\=-131\\$

$f(-2) = -(-2)^3+2(-2)^2+2(-2)+1\\=13$

Average slope of this function is change of f(x) in (-2,6)/change of x in (-2,6)

= $\frac{-131-13}{8} \\=-18$

By mean value theorem there exists a c such that f'(c) = -18

i.e. $-3x^2+4x+2 =-8\\3x^2-4x-10 =0\\$

Using quadratic formula

x = 2.61, -1.277

Out of these only 2.61 lies in the given interval

c = 2.61
