Finding an Equation of a Tangent Line In Exercises 45-50, (a) find an equation of the tangent line to the graph of the function at the given point, (b) use a graphing utility to graph the function and its tangent line at the point, and (c) use the tangent feature of a graphing utility to confirm your results. See Example 10. y = 3 x ( x 2 − 2 x ) ; ( 2 , 18 )

A company's profit is linearly related to the number of items the company sells. Profit, P, is a function of
the number of items sold, x. If the company sells 3000 items, its profit is $10,600. If the company sells
4000 items, its profit is $15,000.
Find an equation for P(x).
P(x) =
Use your equation to determine the profit if the company sells 5220 items.

Sketch the graph of the function
In Exercises 43 and 44, graph the functions. Notice in each case
that the numerator and denominator contain at least one com-
mon factor. Thus you can simplify each quotient; but don't lose
track of the domain of the function as it was initially defined.
