Let f(x) = 3,x. a.) Find the value of c that satisfies the conclusion of the Mean Value Theorem on x E [1, 9]. b.) Find the equation of the tangent line to f(x) at x = c (from part a). Call this line y1. c.) Find the equation of the secant line between x = 1 and x = 9. Call this line y2. d.) Use Desmos to graph f(x), y1, and y2 on the same screen. (Make sure the lines look like they "should" look.) https://www.desmos.com/calculator You will need to turn in your solutions to parts a, b, and c and a screenshot of your graph from part d. + Drag and drop an image or PDF file or click to browse
