$\"\"$

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 the 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 for all values of $\"\"$ on the interval $\"\"$ .

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

The discontinuity is not shown in the graph.

$\"\"$

The function has a discontinuous at $\"\"$ .
