Let f(x) = Ð9xÐ. For the area above the x-axis and between the lines x= -9 and x=18

a. draw and label a sketch with

the area shaded

b. find the area of the region in

the xy-plane under the graph

of f(x)

Sorry it came out that way:

Let f(x) =|9x|. For the area above the x-axis and between the lines x= -9 and x=18
