(a )
\Observe the graph:
\The -coordinate of a point at which the graph crosses or touches the
-axis is an
-intercept.
The graph touches -axis at
.
The -intercept 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 on the graph.
So the graph is 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.
\The function is symmetric with respect to the -axis.
(a ) Intercept is .
(b ) Symmetric with respect to the -axis.
