15 a. How close does the curve y = J; come to the point [TD] ? (Hint: It the square of the distance is minimized, square roots can be avoided.) b. Graph the distance function D{x} (the square of the distance) and y = 4; together and reconcile the result with the result in part (a). 15 a. First determine the function D(x}, the square of the distance, from the curve I} = J; to the point [H] whose value must be minimized. 2 D(x} = D
