Question

Given f (x) = 17 minus x squared, what is the average rate of change in f(x) over the interval [1, 5]? –6 Negative one-half One-fourth 1

Answer 1

Answer

-6

Step-by-step explanation:

We know that  the average rate of change of the function f(x) over the interval [a,b] is equal to ( f ( b ) - f ( a ))/ (b - a). In this problem f(x) = 17-x². interval [a,b] ----> [1,5], so for x = 1       f(1) = 17-1²=16.    and for x=5        f(5) = 17-5²= -8.    Substitute the values of ( f ( b ) - f ( a ))/ (b - a), to be (-8 - 16)/ (5 - 1) which gives you your answer of -6.
