Find the stationary points of y = (x² – 2x³)e²x. Note: you must give exact values - do not approximate the stationary point values Draw a single sign table and an accompanying sign diagram. For each interval in the sign table, select a value of x and show all working to obtain the sign of the gradient in that interval. Note: there should be no approximations in working to obtain gradient for the selected values of x. Please leave the expressions with square roots and powers of e.
