A'(1, -4)

B'(3, 2)

C'(4. -2)

Explanation:

Given

Triangle ABC with coordinates

A(1, 4), B(3, -2), C(4, 2)

To find

Coordinates of the image A'B'C' after a reflection over the x-axis

Solution

Rule for reflection over x-axis is

R(x) = (x, y) → (x, -y)

The coordinates will change as follows

A(1, 4) → A'(1, -4)

B(3, -2) → B'(3, 2)

C(4, 2) → C'(4. -2)
