Question

what rule maps figure a onto figure c? (1 point) $r_{90^{circ}}$ $r_{y - axis}$ $r_{y = 0}$ $r_{x - axis}$

Explanation:

Step1: Observe the transformation

By looking at the graph, we can see that Figure A and Figure C are mirror - images of each other across the y - axis.

Step2: Recall transformation rules

The rule for reflection across the y - axis is $(x,y)\to(-x,y)$. In transformation notation, reflection across the y - axis is denoted as $r_{y - axis}$.

Answer:

The rule that maps Figure A onto Figure C is $r_{y - axis}$.
