how do we evaluate a table of x, and f(x) without being given the function, using the midpoint rule?
Eg. when x=2, f(x)=4. when x= 5/2, f(x) = 9, etc etc. say we have this table, and we are to evaluate it from 2 to 5. deltaX = 1/2. midpoints are 2.25,2.75,3.25,3.75,4.25,4.75... I don't know what f(x) at these points are. Should I just make a graph and estimate it?

Approximating Areas and Distances

I recommend starting with a sketch of the function.
Determine the correct width for the approximating rectangles.
Draw in the first couple, and last, approximating rectangles.
Be careful to include the correct function evaluation for each height.
