Question

I am unsure about how to answer part b and c of the attached question.

Let f(t) be the piecewise linear function with domain 0 <t<8shown in the graph below (which is determined by connecting the dots). Define a function A(x) with domain 0 < x < 8 by
A(x)=
f(t) dt.
Notice that A(x) is the net area under the function f(t) for 0 <t < x. If you click on the graph below, a full-size picture of the graph will open in another window.
