7. the letter
is shown on the graph grid below. transform the image using the function f shown below.
did this transformation preserve the size and shape of
the image? use tracing paper if necessary.

See explanation

Step-by-step explanation:

Shown letter E has endpoints at (-3,1), (-6,1), (-4,4), (-6,4), (-3,7) and (-6,7). The transformation with the rule

maps these points into points

(1,-3), (1,-6), (4,-4), (-6,4), (7,-3) and (7,-6) (see attached diagram)

This transformation is a reflection across the line y=x. Reflection preserves the figure size and shape.

Yes, this transformation preserve the size and shape of the image.

The figure is reflected across the line y=x.

Step-by-step explanation:

From the given figure it is clear that the vertices and end points of the figure are (-3,1), (-6,1), (-4,4), (-6,4), (-3,7) and (-6,7).

Rule of transformation is

Using the rule of transformation we get

The vertices and end points of the figure are (1,-3), (1,-6), (4,-4), (4,-6), (7,-3) and (7,-6).

Plot these points of the coordinate plane.

Yes, this transformation preserve the size and shape of the image.

The figure is reflected across the line y=x.
