<u>ANSWER TO PART A</u>
The given triangle has vertices
The mapping for rotation through counterclockwise has the mapping
Therefore
We plot all this point and connect them with straight lines.
ANSWER TO PART B
For a reflection across the y-axis we negate the x coordinates.
The mapping is
Therefore
We plot all this point and connect them with straight lines.
See graph in attachment
b is decreased by 25% which means there will be (-ve) sign.
