Question

The figure above the x-axis is the preimage. The figure below the x-axis is the image. Which transformation produced the image?

Answer 1

Transformation :
`(x,y)\rightarrow (x,-y)`

Explanation:

We are given pre-image is above x-axis abd original figure below x-axis.

As we know y-axis below x-axis always negative. When we translate about x-axis only y value of each coordinate change.

x-coordinates remain same.

Best transformation for below x-axis to above x-axis would be
`(x,y)\rightarrow (x,-y)`.

For example, (2,-3) change to (2,3)

This is valid to all types of figures which form below x-axis.
