$\"\"$

The function is $\"\"$

Graph the function on the interval $\"\"$ .

$\"\"$

Observe the graph:

The function $\"\"$ is continuous on the interval $\"\"$ .

$\"\"$

The function is $\"\"$ .

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

$\"\"$ .

The function is continuous for all values of $\"\"$ , except at $\"\"$ .

The function is discontinuous at $\"\"$ on the interval $\"\"$ .

$\"\"$

In Graphical representation the function $\"\"$ is continuous on the interval $\"\"$ .

But analytically the function $\"\"$ is discontinuous at $\"\"$ on the interval $\"\"$ .

The discontinuity is not shown on the graph.

$\"\"$

The function has discontinuity is at $\"\"$ .
