Document Summary

Problem 1 (a) a function f is de ned by the table x. Sketch the graph of f using the axes below. Exam 1 solutions (b) a function g is de ned by the graph y. Describe the function g with a table. x. Suppose functions f and g have formulas f (t) = t + 3 and g(t) = t 4 t 2 (a). What is the domain of f ? all real numbers, i. e. , r (b). What is the domain of g? all real numbers except 2, i. e. , t (cid:54)= 2, or r {2}, or r/{2}, or . (c). Evaluate f (0). f (0) = 0 + 3 = 3 (d). Evaluate (f + g)(0). (f + g)(0) = f (0) + g(0) = 3 + Evaluate (f g)(0). (f g)(0) = f (0)g(0) = 3 2 = 6 (cid:18) g (cid:19) f (cid:18) g (cid:19) (f).
