The coordinates of the image of point E after the sequence of transformations are (-5, 0).

In this exercise, we would apply a translation 4 units down to the pre-image, in order to determine the coordinates of its image as follows;

(x, y) → (x, y - 4)

Point E (5, 4) → (5, 4 - 4) = Point E' (5, 0).

Furthermore, the mapping rule for the counterclockwise rotation of a geometric figure about the origin by 180° can be modeled by this mathematical expression:

(x, y) → (-x, -y)

Point E' (5, 0) → Point E" = (-5, 0)

In conclusion, we can logically deduce that the coordinates of the image of point E after translating the pre-image down 4 units and rotating 180° counterclockwise are (-5, 0).

Complete Question:
