Question

a triangle was translated 4 units down.
in the graph, which figure is the pre-image and which figure is the image?
○ $\triangle fgh$ is the image and $\triangle abc$ is the pre-image
○ $\triangle fgh$ is the pre-image and $\triangle abc$ is the image.
○ both triangles are images.
○ the image cannot be determined from the graph.

Explanation:

A translation 4 units down means the pre-image is the original figure, and the image is the figure shifted 4 units lower along the y-axis. $\triangle FGH$ is positioned above $\triangle ABC$, so shifting $\triangle FGH$ 4 units down results in $\triangle ABC$.

Answer:

$\boldsymbol{\triangle FGH}$ is the pre-image and $\boldsymbol{\triangle ABC}$ is the image.
