Exercise 2.3.5
The leading coefficient is \(1\), which is a positive number. This means that the graph of the function on the interval to the right of the largest \(x\)-intercept lies above the \(x\)-axis. Since the graph crosses the \(x\)-axis at \(1\) and \(2\), but does not cross at the \(x\)-intercept at \(-1\), the graph will look like the following:
