Question
Let f(t) be the piecewise linear function with domain 0 <t < 8 shown in the graph below (which is determined by
connecting the dots). Define a function A(x) with domain 0 <x < 8 by
:| f(1) dt.
A(x)
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.
