Q. Given the function h(x)=x2−6x+1, determine the average rate of change of the function over the interval −1≤x≤4.Answer:
Given Function and Interval: We are given the function h(x)=x2−6x+1 and asked to find the average rate of change over the interval [−1,4]. The average rate of change is calculated using the formula:Average rate of change = (h(b)−h(a))/(b−a)where a and b are the endpoints of the interval. In this case, a=−1 and b=4.
Calculate h(a): First, we need to find the value of h(a) where a=−1. h(−1)=(−1)2−6(−1)+1 h(−1)=1+6+1 h(−1)=8
Calculate h(b): Next, we need to find the value of h(b) where b=4.h(4)=(4)2−6(4)+1h(4)=16−24+1h(4)=−7
Calculate Average Rate of Change: Now we have both h(a) and h(b), so we can calculate the average rate of change.Average rate of change = b−ah(b)−h(a)Average rate of change = (4)−(−1)(−7)−(8)Average rate of change = 5−15Average rate of change = −3
