Answer:

This would be a reflection over the x-axis and a vertical stretch by a factor of 3.

Step-by-step explanation:

We can identify the shift over the x-axis by looking at the negative in the front.

We can identify the vertical stretch by noting that the variable is being multiplied by 3, which makes the y value go up 3 times as fast.
