11. For the graph pictured: (2 points each part, 8 total) a. State the open interval(s) on which \( f^{\prime}(x)>0 \) b. State the open interval(s) on which \( f^{\prime}(x)<0 \) c. State the open interval(s) on which \( f^{\prime \prime}(x)>0 \) d. State the open interval(s) on which \( f^{\prime \prime}(x)<0 \) BONUS (optional, priced as marked, fit 'em in where you can): Verify the function in \( \# 2 \) satisfies the conditions of the Mean Value Theorem. \( (+1) \)
