The revenue, \(y\) dollars, of a company for selling \(x\) items is given by \(y=80x-x^2\), for \(0\leq x\leq80\).

1. Sketch the graph of \(y=80x-x^2\) for \(0\leq x\leq80\), showing its turning point and its \(x\)- and \(y\)-intercepts.[2]
2. The company claims that it is possible to make a revenue of $2000. Using your graph, determine whether this statement is correct.[1]
