Question 1. Differentiation
1. Consider the function f(x)= 2-e on [-1,1], and a point a € [-1,1]. Consider the triangle formed by the
tangent line to f at a, and the lines z= 0 and y=0. Find the points a such that the triangle has an area of
exactly 4/e. If necessary, approximate the value a to 3 places after the decimal.
2. Suppose that the tangent line to the graph of f(x) = (6) at r= 1 is equal to the tangent line to the graph
of g(x) = 2ln(e2+e-2²)-2 ln(2)-1 at z=0. What is the value of the positive constant b, and what is the
equation of the tangent line?
