Practice Exam 3 Please hand only only clearly written work, not scratch paper. Clearly mark your ﬁnal an
swers for each problem. Partial credit will only be given on problems for which your work is clearly shown.
The only allowable materials for this exam are paper, pens and pencils. No notes, textbooks or calculators will be allowed. (1) Suppose that :v and y satisfy the equation: my = 1n(:1:) Find the slope of the tangent line to the graph of this equation at the point (e, 0).
