In Exercises 9-12, say whether or not f ( x ) is defined for the given values of x. If it is defined, give its value. [ Hint: See Quick Example 3.] f ( x ) = x − 1 x 2 , with its natural domain a. x = 4 b. x = 0 c. x = − 1

Solution Summary: The author explains that the function f(x) is defined at x=4 in its natural domain. If it is not defined give its value.
A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall? You may use a calculator.
