Question

Look at the graph below. What is the average rate of change between 11 and 14 seconds?

Answer 1

-4/3 m/s

Explanation:

The average rate of change is slope because

`\frac{\int\limits^a_b {((d)/(dx)f(x)) } \, dx}{b-a} =(f(b)-f(a))/(b-a)`

so

`(f(14)-f(11))/(14-11)= (6-10)/(3) = (-4)/(3)`

i'm assuming the units would be meters/sec

so -4/3 m/s
