Let f(x,y) = 2x2+ y2 - 5x - 8y+3. (A) Find the minimum value of f(x,y) when y = 2. (B) Explain why the answer to part (A) is not the minimum value of the function f(x,y). . . . . . (A) The minimum value of f(x,2) is (Simplify your answer.) (B) The answer to part (A) is not the minimum value of the function f(x,y) because the minimum value of for example, is , which is less than the answer to part (A). (Simplify your answer.)
