a. Suppose that the inequalities

hold for values of x close to zero. (They do, as you will see in Section 9.9.) What, if anything, does this tell you about

Give reasons for your answer.

b. Graph the equations y = (1/2) – (x²/24), y = (1 - cos x)/x², and y 1/2 together for -2 ≤ x ≤ 2. Comment on the behavior of the graphs as
