Answer:
Step-by-step explanation:
For the limit of a function to exist, then the right hand limit of the function must be equal to its left hand limit as shown;
If the function is f(x), for f(x) to exist then;

Given the function;

Lets check if the above statement is true.
The right hand limit of the function occurs at x> 9
f(x) = 9-x

The left hand limit occurs at x<9
f(x) = x+9

From the above calculation, it can be seen that
, this shows that the function given does not exist at the given point.

=4/3
II hope this helps it’s pretty simple
