In Exercises 112, each graph is a slight variation on the graph of one of the twelve basic functions described in this section. Match the graph to one of the twelve functions (a)(l) and then support your answer by checking the graph on your calculator. (All graphs are shown in the window by .) (a) (b) (c) (d) (e) (f) (g) (h) (i) (j) (k) (l) 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. In Exercises 1318, identify which of Exercises 112 display functions that fit the description given. 13. The function whose domain excludes zero 14. The function whose domain consists of all nonnegative real numbers y = 2- 4/11 + e-x 2 y = - 2x y = int1x + 12 y = x - 2 y = -1/x y = -x y = 1x - 122 y = x 3 y = 1x + 22 + 1 3 y = ex y = -sin x y = cos x + 1 - 2
