(a )

Observe the graph :

The -coordinate of a point at which the graph crosses or touches the -axis is a -intercept.

The graph touches -axis at .

The -intercepts of the graph is .

The -coordinate of a point at which the graph crosses or touches the -axis is a -intercept.

The graph touches -axis at  .

The -intercept of the graph is .

(b )

For instance, is on the given graph.

Symmetry about the -axis : .

is not on the graph.

So the graph is not symmetric about the -axis.

Symmetry about the -axis : .

is not on the graph.

So the graph is not symmetric about the -axis.

Symmetry about the origin : .

is not on the graph.

So the graph is not symmetric about the origin.

There is no symmetry for this function.

(a ) Intercepts are  is and .

(b ) No symmetry.
