Find the stationary points of y = (:r.'1 29:3)e23. 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 :r: and show all working to obtain the sign of the gradient in that interval. Note: there should he no approximations in working to obtain gradient. for the selected values of 3:. Please leave the expressions with square roots and powers of e
