Can someone help me pls!

Is this right... heres the questions
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).

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.
Heres my answer:
A(1,4)=A(1,-4)
B(3,-2)=b(3.2)
D(4,2)=D(4,-2)

somewhat agree,

your presentation of the answer however, makes no sense

you should say something like
A(1, 4) ----> A'(1,-4) etc ,

A(1,4) = A(1, -4) is gibberish
