Graph the function by hand, not by plotting points, but by starting with the graph of one of the standard functions given in Section 1.2, and then applying the appropriate transformations. 9. y = -x 10. y = (x - 3) 11. y = x + 1 12. y = 1- 13. y = 2 cos 3x 15 y=x - 4x + 5 17. y=2-x 19. y = sin(x) 21. y = |x-2| 23. y =x-1| 14. y = 2x + 1 16. y = 1+ sin #x 18. y = 3 - 2 cos x 20. y = |x|- 2 1 22. y = tan 24. y = | cos x| - 4 -TE
