9. Use the limit process to find the area of the region between the graph of the function f(x) = -x' + 9 and the x-axis over the interval [0, 3]. 10. A ball is thrown vertically upward from the ground with an initial velocity of 40 feet per second. How high will the ball go? CALCULUS I MAT281 Chapter 4 In-Class 1 1. Given that of(x)dx = -9 and J, f(x)dx = 3 find fif(x)dx . 12. Find the area of the region bounded by y = (x + 2)2 - 1, the x-axis, x = -1, and x = 2. 13. Use the Fundamental Theorem of Calculus to evaluate: m/2 CSC2 x dx 14. Consider F(x) = Itt's Find F' (x) and F' (-2) . 15. Find Jx2(2x3 + 4)5 dx
