Finding the Zeros of a Polynomial Function In Exercises 17-36, find all the zeros of the function and write the polynomial as a product of linear factors. Use a graphing utility to verify your results graphically. (If possible, use the graphing utility to verify the imaginary zeros.) 17. h(x) = 12 - 4x + 1 18. g(x) = 1 + 10r + 23 19. f(x) = x2 - 12x + 26 20. ((x) - 2 + or - 2 21. f(x) = x2+ 25 22. f(c) = 2 + 36 23. f(x) = 16x4 - 81 24. f(v) = 8ly- 625 25. f(z) = 23 - z + 56 26. hol - 5 - 4 - 3 27. f(x) = x4 + 10x2+ 9 28. flu) = x* + 29x- -+ 100 29. f(x) = 3.13 - 512 + 48.x - 80 30. f(x) = 3x3 - 2x2 + 75x - 50 31. f(1) = 13 - 312 - 15/ + 125 32. f(x) = x3 + 11x2 + 39x + 29 33. f(x) = 5x3 - 9x2 + 28r + 6 34. f(s) = 3s3 - 452+ 85 + 8 35. g(x) = x4 - 4x3 + 812 - 16x + 16 36. h(x) = x4 + 6x3 + 10x2 + 6r + 9
