help with area under the curve using right end point
.Approximate the area under the curve on the given interval using rectangles and right-endpoint evaluation. Round to three decimal places.
y-x^(3)-1 on [1,4], n=100
a)58.704
b)70.381
c)63.000
d)61.698

.
2. Approximate the area under the curve on the given interval using rectangles and right-endpoint evaluation. Round to three decimal places.

y=x^(2)-8 on , [0,2], n=16

a)-14.078
