Use the upper and lower sums to approximate the area of the region using the given number of subintervals (of equal width). (Round your answers to three decimal places.) y = 1 − x2.

The upper sum value is 0.8592

The lower sum value is 0.6592.

Step-by-step explanation:

Given information:

The equation

And

now, first find derivative of the above equation:

As,
