What are the critical points of the function O x = 2 f(x) =-2x3 +3x2+ 36x-68? O x = 1, 6 O x=-2, 3 O x =-4, 9 N Which equation is represented by the following graph? 2 Oy = 2x3 - 5 Y = RX ) Oy = 12 - x 2x2 + 1 y = 2 272 3 Oy= 2 2- 2 *X = 1 12/12/21, 8:42 AM Thinkwell | 501 Test 5: Chapter 8 Curve Sketching Given that the function f(r) has a critical The point is a maximum. point at x = v2 and that the second O The point is a minimum. derivative is undefined at that point, what O No additional information can be determined. can be said about the function at r = V2? The point is a point of inflection. All of the following are true except: Domains must be restricted so that any cusp points are excluded. Domains must be restricted so that expressions underneath radicals with even roots are always non- negative. Domains must be restricted so that fractions with expressions in the denominator are never undefined. Regions of the function which are not in the domain do not need to be graphed
