Suppose that G(x) = log 2 (2x+2)- 3. (a) What is the domain of G? (b) What is G(7)? What point is on the graph of G? (c) If G(x)=-1, what is x? What point is on the graph of G? (d) What is the zero of G? (a) The domain of G is (-1,00). (Type your answer in interval notation.) (b) G(7) = 1 The point (7,1) is on the graph of G. (Type an ordered pair.) (c) If G(x)=-1, then x = 1. The point () is on the graph of G. (Type an ordered pair.)
