f. Determine whether the function y = 5 + 5x – 0.4x² is concave, linear, or convex between points a = (4, 18.6) and c = (9, 17.6) by evaluating the following relationship: Of (xa)+(1-0)f (x.)<=2 f(0x, +(1–0)x.). Use0 = 0.5 initially, but then try 0 = 0.25. g. Verify your answer to part f) using calculus.
