Can someone please show me the steps to this problem...Thanks in advance.
Let f(x) = Ð9xÐ. For the area above the xaxis 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 xyplane under the graph
of f(x)

describe in words what Ð9xÐ is supposed to be.
On my Mac it came out weird. 
Sorry it came out that way:
