To determine the symmetry of the graph of the equation
, we need to check for symmetry with respect to the x-axis, y-axis, and the origin.1. **Symmetry with respect to the x-axis**: For a graph to be symmetric about the x-axis, replacing
with
should yield an equivalent equation. Let's test this:
Replace
with
:
This is not equivalent to the original equation
. Therefore, the graph is **not** symmetric about the x-axis.2. **Symmetry with respect to the y-axis**: For a graph to be symmetric about the y-axis, replacing
with
should yield an equivalent equation. Let's test this:
Replace
with
:
This is not equivalent to the original equation
. Therefore, the graph is **not** symmetric about the y-axis.3. **Symmetry with respect to the origin**: For a graph to be symmetric about the origin, replacing
with
and
with
should yield an equivalent equation. Let's test this:
Replace
with
and
with
:
This is not equivalent to the original equation
. Therefore, the graph is **not** symmetric about the origin.Since the graph is not symmetric with respect to the x-axis, y-axis, or the origin, the correct answer is:D. none of these
