12. The slope of the secant line to the graph of g ( x ) between x = 5 and x = 5 + h is 10 – 6 h + 2 h 2 . What is the slope of the tangent line at x = 5? 13. Let f ( x ) be a function with x -intercepts at x = 2 and x = -4 and with horizontal tangents at x = 3 and x = 5. Additionally, g ’(1) = 1 and g (0) = 1. Let g ( x ) be ln( f ( x )). At what point(s) does g have a horizontal tangent? 14. If the marginal profit for manufacturing widgets is -$20/widget, what does this mean?
