Given that

The vertices of the polygon ABCD are A(1,1), B(2,3), C(3,2), and D(2,1). ANd it is reflected about the x-axis.

So we have to find the vertices of the polygon A'B'C'D'.

Explanation -

Since the reflection is about the x-axis, the x-axis will be unchanged and the y-axis will be changed.(sign will be changed)

And it will be changed by the factor +2 in upwards directions.

So if A, B, C, D are reflected across x-axis.

The new points will be A' = (1,-1)

B' = (2,-3)

C' = (3,-2)

D' = (2,-1)

Now we have to add 2 in the y axis as they move upwards.

Then, the required points will be

A' = (1, -1+2) = (1,1)B' = (2, -3+2) = (2,-1)C' = (3,-2+2) = (3,0)D' = (2, -1+2) = (2,1)So these are the required answers.
