A table of values for a continuous function f is shown below.

Question

If four subintervals are used, which of the following is the right sum approximation of ∫ fxdx (x=0 to x=2)?

x: 0 0.5 1.0 1.5 2.0

y: 4 6 8 12 22

A) 6

B) 12

C) 24

D) 48

E) 60

Answer 1

The right hand sum is 6(0.5) + 8(0.5) + 12(0.5) + 22(0.5) = 24
