The map Figure M onto Figure N, we need to perform the following transformations:

Reflection across the x-axis. This flips Figure M upside down.

Rotation 180 degrees clockwise about the origin. This turns Figure M upside down and around.

Translation 3 units upward. This moves Figure N up so that it is centered on the y-axis.

The steps above can be summarized as follows:

R_180 * R_x * T_up(3)

where:

R_180 is a rotation of 180 degrees clockwise about the origin

R_x is a reflection across the x-axis

T_up(3) is a translation 3 units upward

Here is a diagram that illustrates the transformations:

M -> R_x(M) -> R_180(R_x(M)) -> T_up(3)(R_180(R_x(M))) = N

We can also describe the transformations using coordinate geometry. Let (x,y) be a point in Figure M.

Then, the following transformations will map (x,y) to the corresponding point (x ′ ,y') in Figure N:

x' = x

y' = -y - 3

This can be written as a single matrix transformation as follows:

[[1, 0], [0, -1]] * [x; y] + [0; -3]

This matrix transformation first reflects the point (x,y) across the x-axis, then rotates it 180 degrees clockwise about the origin, and finally translates it 3 units upward.
