The limit does not exist at x = 2 because the function is not continuous at any x value.
The limit does not exist at x = 2 because the function approaches different values from the left and right side of 2.
The limit does not exist at x = 2 because the function value is undefined at x = 2.
The limit does not exist at x = 2 because the function does not approach f(2) as x approaches 2.The limit exists at x = 2.
(b)
lim x→1 h(x)
L =

The limit does not exist at x = 1 because the function does not approach f(1) as x approaches 1.
The limit does not exist at x = 1 because the function approaches different values from the left and right side of 1.
The limit does not exist at x = 1 because the function is not continuous at any x value.
The limit does not exist at x = 1 because the function value is undefined at x = 1.The limit exists at x = 1.
