2-101.

Given

*y*=for 4 ≤*x*≤ 6: Homework Help ✎Divide the interval [4, 6] into 5 equal pieces. What is the width of each rectangle?

Find

*x*_{0},*x*_{1},*x*_{2},*x*_{3},*x*_{4}, and*x*_{5}.Use 5 rectangles to get upper and lower bounds for the area under the curve.

What minor change could you make to part (a) to make the upper and lower bounds closer together?

*x*_{0} = 4

Now add the width to *x*_{0} to find *x*_{1}. Continue the same for the last two.
