(9 points) Now look back at all the pairs of graphs and derivatives that you've drawn in questions 2 - 5, and fill in the blanks with one of the following phrases (an answer can be used more than once and not all answers need to be used.) has a horizontal tangent line is below the x-axis is increasing is above the x-axis is decreasing equals zero has a vertical tangent line is undefined a. In regions where f (x) slopes upward from left to right, f' (x) b. In regions where f (x) slopes downwards from left to right, f'(x) c. At x values where f (x) has a sharp corner, f' (x)_ d. At x values where f (x) is discontinuous, f' (x). e. At x values where f' (x) = 0, f(x) f. At x values where f'(x) is positive, f (x) g. At x values where f'(x) is negative, f(x) h. At x values where f (x) has a peak or a valley, f' (x ) or f' (x )
