Explain why the following justification is incorrect: To evaluate the limit of the function x² + y² 2 lim (x,y) →(0,0) 1+ y² we can approach the point (0,0) along different paths and see if the limit is the same regardless of the path taken. First, let's consider the path along the x-axis ($y = 0$). We have: x² + 0² lim (,0) (0,0) 1+0² lim (x,0) (0,0) 1 Next, let's consider the path along the y-axis ($x = 0$). We have: 0² + y² lim (0,y) →(0,0) 1+ y² = 0. y² lim (0,y) (0,0) 1+ y² = 0. Since the limit is 0 along both paths, we can conclude that the limit of the given function as (x, y) approaches (0, 0) is 0. Enter your answer here

Explain why the following justification is incorrect:
To evaluate the limit of the function
x² + y²
lim
(x,y) →(0,0) 1+ y² ¹
we can approach the point (0,0) along different paths and see if the limit is the same regardless of
the path taken.
First, let's consider the path along the x-axis ($y = 0$). We have:
x² + 0²
lim
(x,0) (0,0) 1+0²
x²
lim
(x,0) (0,0) 1
Next, let's consider the path along the y-axis ($x = 0$). We have:
0² + y²
lim
(0,y) →(0,0) 1+ y²
=
y²
lim
(0,y) →(0,0) 1+ y²
= 0.
-
0.
Since the limit is O along both paths, we can conclude that the limit of the given function as (x, y)
approaches (0, 0) is 0.
