8. Using the second derivative test, nd the maximum and minimum points for the function f {x)=x" 8x2+5 9. What conclusion can be made if: a. Afunction changes from a decreasing interval to an increasing interval. b. lim =m and lim :00 Mfr) Milt) 10 If the minimum of the function y= x2 4x +21 occurs at x = 2, what are the coordinates of ' the minimum point?? 11. When nding one-sided limits what does 0+ imply? 12. When does a limit not exist? 13. What conditions must be met if a function is said to be continuous? 14. Use the curve sketching procedure to analyze the function. a. y =x3 +x2 20x _1+x2 _ 2 b' y 1x Show all work for each question. 1.
