Answer:
• for x = 2a√t, make t the subject:
• then find y:
<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.
