Calculus Graphing with the Second Derivative Examples of Curve Sketching 1 Answer Nallasivam V Refer Explanation section Explanation Given #y=x^32x^2x# #dy/dx=3x^24xAt x = 1, y = x 3 2x 2 = (1) 3 2(1) 2 = 1 2 = 3 Thus the graph of y = x 3 2x 2 is below the xaxis at x = 1 The important point here is that the graph is thus below the xaxis for all x satisfying x < 0 since to go above the xaxis the graph would need to cross the xaxis and it doesn't touch the xaxis until x = 0Exponential probability distribution Useful for modeling the lifetime of electronic components A continuous rv Xfollows the exponential probability distri
