20- - 9 Consider the function g defined by g(a) = for x * 3. a - 3 Our goal is to understand the behavior of g near x = 3. a) As a approaches 3 this gives an indeterminate form of the type 0 00 0 00/00 0 0 X 00 0/0 0 10 0 00 - 00 Suppose first that a > 3. b) If a > 3, then |x - 3 = FORMATTING: Your answer should not have an absolute value. Therefore, when x > 3 we may simplify the expression for g(a) to get g(20) = Hence, lim g(x) = Suppose now that x
