Chapter 3, Problem 37(choose chapter or problem)
(a) Make a conjecture about the shape of the graph of \(y=\frac{1}{2} x-\ln x\), and draw a rough sketch.
(b) Check your conjecture by graphing the equation over the interval \(0<x<5\) with a graphing utility.
(c) Show that the slopes of the tangent lines to the curve at \(x=1\) and \(x=e\) have opposite signs.
(d) What does part (c) imply about the existence of a horizontal tangent line to the curve? Explain.
(e) Find the exact x-coordinates of all horizontal tangent lines to the curve.
