a reflection then translation.

answer:

43

step-by-step explanation:

estimate the area under the curve f(x) = 16 - x^2 from x = 0 to x = 3 by using three inscribed (under the curve) rectangles

first we find out the width of the rectangle

δx=b−a/n,   a= 0 and b= 3, n= 3

so δx= 1

divide the interval [0,3] into   3 sub intervals of width=1

[0,1]     [1,2]     [2,3]

now we plug in end point and evaluate the function

we take left endpoints

f(0) = 16 - 0^2=16

f(1) = 16 - 1^2= 15

f(2) = 16 - 2^2= 12

now sum = δx(f(0) + f(1)+f(2))

= 1 (16+15+12)= 43
