Question

Estimate the area under the curve f(x) = x2 from x = 1 to x = 5 by using four inscribed (under the curve) rectangles. Answer to the nearest integer.
1 to 5 is 4 units, so each rectangle is one unit wide

the height of each rectangle is x^2
... x equals one to four ... under the curve

find the combined area
Shouldn't it specify of you are going from the left or the right?
The answers 30, dont ask how I got it
30 is the correct answer.
