Evaluate the following limit. lim ef(x,y)²-6g(x,y) (x,y)→(2,5)

3-8x x→∞ 3x²-2 19. Find the limit lim

Evaluate the following limit. 4y² - 196 lim (x,y) →(7,7) xy-7x Select the correct choice and, if necessary, fill in the answer box within your choice. 4y² - 196 lim (x,y) (7,7) xy-7x B. The limit does not exist. A. (Simplify your answer.)

Find the limits as x→ o and as x → -oo. y = f(x) = 5x3 – x4 lim f(x) = lim f(x)
