Question

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

Answer 1

Answer:

-4/3 m/s

Step-by-step explanation:

The average rate of change is slope because

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

so

$\frac{f(14)-f(11)}{14-11}= \frac{6-10}{3} = \frac{-4}{3}$

i'm assuming the units would be meters/sec

so -4/3 m/s
