2. Given two functions f(x) = x2 and g(x) = x3 - x2. At the points where the U two functions intersect, there exists a common tangent at only one of these points. Determine the coordinates of the point where the common tangent exists. Note: All work must be shown using calculus concepts and only rules learned in this unit. If you use any rules for the slope of the tangent, you cannot use them. 2b. At the "other" x value where there is no common tangent, determine the equation of the tangent at this point to the curve y = x3 - x2
