20. 21. 22. 23. Determine whether the function is even, odd or neither. Do 5 of the problems graphically and the remaining 5 problems analytically (using algebra!). 24. 25. 26. 27. In exercises 43 46, write a piecewise formula – 28. 29. for the function. Your answers should look like 30. 31. problems 36 38 from this section. – 32. 33. 43. In exercises 34 38, (a) draw the graph of the – function, find the (b) domain and (c) the range. 34. 35. 36. 37. 38. 44. In exercises 39 42, use the vertical line test to – determine whether the curve is the graph of a function. 39. 40. 45. 46. 41. In exercises 47 and 48, find (a) (b) (c) 42. (d) (e) (f)
