The right arrow symbol used to show the transition from a point to its image after a transformation is not contained within the Equation Editor. If such a symbol is needed, type "RightArrow." For example: P(0, 0) RightArrow P′(1, 2).

Geessshhh, how about just like this instead of all that gibberish:

Triangle ABC has coordinates
A(1,4); B(3,-2); and C(4,2).

Find the coordinates of the image
A'B'C' after a reflection over the x-axis.

Would it not have been a good idea to make a sketch of what would happen?

all x values would stay the same and y would go its opposite

A(1,4) ---> A'(1, -4)
B(3,-2) ----> ......
C(4,2) -----> .....
It would of have NOT been a good idea to draw a sketch. You can’t even post anything on here. What’s the use of making a sketch if you can’t even post it
