If , what is the average rate of change of f(x) over the interval [1, 5]?

step-by-step explanation:

by definition, the average rate of change of any function f(x) in any given closed interval [a,b] is:

so, applying that definition here, we see that here a=4 and b=13.

therefore, the average rate of change in f(x) over the interval [4,13] will be depicted as:

thus,   is the correct answer.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
