there are the four intervals, they each have length $\frac{1}{2}$ and the midpoits (lets use decimals, easier to write) are 
$$.25,.75,1.25,1.75$$

anonymous · Answer

your job is to evaluate the function at those numbers, add them up, then multiply the result by $.5$

anonymous · Answer

it is a calculator exercise for sure
have fun

anonymous · Answer

So when it says m4, it isn't referring to only the last section?

anonymous · Answer

i think they are calling M4 your answer
midpoint with 4 intervals
just a guess though
