WebTo visually determine if a limit exists as x approaches a, we observe the graph of the function when x is very near to x = a. In Figure 5 we observe the behavior of the graph on both sides of a. Figure 5 To determine if a left-hand limit exists, we observe the branch of the graph to the left of x = a, but near x = a. This is where x < a.

WebJul 28, 2015 · When y = 0 or x = 0 then lim ( x, y) → ( 0, 0) f ( x, y) = 0. When y = x 2, we also have that lim ( x, y) → ( 0, 0) f ( x, x 2) = 0. So I believe the limit exists and is zero, and I want to prove it now by using the definition. So let ϵ > 0. Then we need to find a δ > 0 such that if 0 < x 2 + y 2 < δ, then x 2 y 2 x 2 + y 4 − 0 < ϵ.

WebJan 2, 2024 · The existence of a limit does not depend on what happens when x equals a. Look again at Figure and Figure. Notice that in both graphs, as x approaches 7, the output values approach 8. This means lim x → 7 f ( x) = lim x → 7 g ( x). Remember that when determining a limit, the concern is what occurs near x = a, not at x = a.
