Expert Solution

Answer to Problem 11E

The average rate of change of function is 5 .

Explanation of Solution

Given information :

A function is h(t)=t2+2t for t=1,t=4

Formula used :

The average rate of change of a function is defined by, h(t2)h(t1)t2t1

Calculation :

The function is h(t)=t2+2t for t=1,t=4

Put the values of t1=1 and t2=4 into the formula

  h(4)h(1)(4)(1)[42+(2×4)]((1)2+(2×(1)))4+124(1)5255=5
