i need help with questions 20-31 please!

abo mini wag Describe the end behavior of each function. WW glen 20. y = >3 + 2x- + x -1 21. y =8-x3-2x 22. f (x) = x10 - x9 + 5x8 23. g(x) = (x - 3)2 - 11 24. y 1 25. f(x) = -3+2 phing Graph each function. Determine the interval(s) for which the function is ulator increasing and the interval(s) for which the function is decreasing. 26. y = x3 + 3x2 - 9x 27. y = -x3 - 2x + 1 28. f(x) = 1 x + 1 -4 29. g(x) = x +5 x - 2 30. y = x2 - 4/ 31. y = (2 x - 3)2 + 1 cations 32.
