Hello I need help with the following: 17,18,19,20,21

17 Use the first and second derivative charts to sketch g(r) = x2 v6 -x2 on [-2, 2). Find any extrema. 18 Use the first and second derivative charts to sketch p(x) = = (r - 5). Find the inflection points. 19 Use the first and second derivative charts to sketch t(x) = 2sin(x) - sin(2x). Find the inflection points.Part IV: Integration 20 Let f"(x) = sin(2x); S'(0) = 8, and / (0) = 0. Find f(r). 21 Use 4 midpoints and 8 left endpoints to estimate the area under f(?) = = I - 1 on [2, 10]. Use the FTC to find the exact area. Sketch the results neatly and accurately
