Select the answer that best describes each statement. (A) If f(x, y) L as (x, y) (a, b) along every straight line through (a, b), then (B) Answer: lim (x,y)(a,b) f(x, y) = L. [Select] [Select] Always true Not always true lim f(x, y) = L (x,y)(a,b) [Select] f is continuous at (a, b). Answer: Select the answer that best describes each statement.
