i need help with parts a b and c and how to properly use the formulas

The figure below shows the derivative F' of F. Let F (0) = 0. F'(x) 12 T 3 6 9 Of the four numbers F(3), F(6), F(9), and F(12) , which is largest? Which is smallest? How many of these numbers are negative? The largest value is F(L The smallest value is F( V of the values is/are negative.\fThe derivative F (t) is graphed in the figure below. Given that F (0) = 8, calculate F (t) for t = 1, 2, 3, 4, 5. O F' (t) 2 3 4 5 Enter the exact answers. F(I)= F (2) = F (3) = F (4) = F (5) =
