Using translation concepts, it is found that:
A. The triangle was reflected over the y-axis.
B. The coordinates for J' are (-5,-4).
What is a translation?
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For item a, we have that the rule applied at each vertex is given by:
(x,y) -> (-x,y).
This rule means that the triangle was reflected over the y-axis.
In item b, supposing point J(5,-4), the image is given by:
(5,-4) -> (-5,-4).
The coordinates for J' are (-5,-4).
