This question concerns the function e} = 41:13 Tea +22 5. {a} Find the exact I and y-coordinates of the stationary points of f. {h} Use the rst derivative test to classify the stationary points that you found in part {a}. {c} Sketch the graph of f, indicating the y-intereept and the points that you found in part {a}. {You should draw this by hand, rather than using any software? and you can use different scales on the two axes if appropriate.) {d} Find the greatest and least value; taken by f on the interval [I], 5]
