Answer:
A) reflection across the y-axis
Step-by-step explanation:
If , then this says that two -coordinates are equal for opposite values of .
Let a point on .
Then .
We also know that and therefore is also a point on the graph.
If you graph [/tex](-a,b)[/tex] and you will see they are symmetrical to each about the -axis.
Example if given both and , then . This means both (2,3) and (-2,3) are points on the graph.
Here is what those two points look like on a Cartesian Plane (please see graph in picture).
