Switkes 0 answersPost by Jason Mannion on November 14, 2011how 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.
