That fact, called the Extreme Value Theorem, is proved on page 164. With a calculator, compute some values as x approaches its limit, and see what happens. With a calculator, the student should try this for some of the limits on pages 124 and 241. Then check your answer by using a graphics calculator to draw the graph. F(0,1/4a) 1/(4a).
