4. Find the limit (if it exists). 1. Let f be the function given by {(x) = m Part A: ung?) Part A: What is the domain of it? Part a; 1L"; {3' Part B: Find the range of f. 5. Use the graph of x) and g(x) to nd each of the following limits (it i exists). 3. The functions f and g are continuous for all real numbers, and g is strictly increasing. The table gives values of the functions at selected values of x. 'he function h is given by h(x) = g(x)) 3. Explain why there must be a value rfor3
