Answer:
Step-by-step explanation:
ANSWER

EXPLANATION
The given function is

When we plug in x=3 into this function, we obtain,

This means that the function is discontinuous at x=3.
We need to simplify the function to obtain,

This implies that,

The graph this function is a straight line that is continuous everywhere.
To graph

we draw the graph of

and leave a hole at x=3.
See diagram in attachment.
Hence the coordinates of hole is
