Answer:
Dilation by a scale factor of 2 followed by a reflection over the y axis.
Explanation:
The Y-axis is the vertical axis. So that cancels out the two about the x-axis. Then I counted the length of both triangles bases. Luckily for this one their bases aren't tilted but just flat. The big one is 6 and the small 3. Since it is going from one to the other you must find what number completes their equation. 3x = 6.
2
So that's how I got the last part of the problem
Sorry if this doesn't make sense. It seems just like ramble but it should help.
