Answer 1

the answer choices are
a) F(8) - F(1) = 31
b) F(8) - F(1) = 35
c) F(8) - F(1) = 32
d) F(8) - F(1) = 33
e) F(8) - F(1) = 34

Answer 2

The problem tells you the integral from 2 to 8 is 28. This means the area under the curve between those numbers is 28 squares. It then asks what is the area under the curve going from 1 to 8. You have to count the number of squares between x=1 and 2
and add that to 28 to get the area under the curve from 1 to 8.
