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.
