Problem 4. R (1 point) Consider the function y = f (x) graphed below. Give the x-coordinate of a point where: A. the derivative of the function is positive: x = 5/4 B. the value of the function is positive: x = 1.5 C. the derivative of the function is largest: x = 0 D. the derivative of the function is zero: x = 2.5 E. the derivative of the function is approximately the same as the derivative at x = 2.25 (be sure that you give a point that is distinct from x = 2.25!): x = 0.25 Note: You can earn partial credit on this
