Step 1: \ \

The function is $\"\"$ . \ \

The domain of a function is all values of $\"\"$ , those makes the function mathematically correct.

The denominator of the function should not be zero. \ \

$\"\"$ \ \

$\"\"$

$\"\"$ .

The domain of the function is all values of $\"\"$ , except $\"\"$ and $\"\"$ .

The function is continuous for all real numbers, except $\"\"$ and $\"\"$ .

Solution: \ \

The function is discontinuous at $\"\"$ and $\"\"$ .
