Question

What is the formula for reflecting over the x axis and the y axis?

Answer 1

To reflect over the x-axis, change f(x) to -f(x)
To reflect over the y-axis, change f(x) to f(-x)

Answer 2

If it is not a function but just a point (a, b), then:
To reflect about the x-axis change the sign of the y-coordinate . (a, b) becomes (a, -b).
To reflect about the y-axis change the sign of the x-coordinate . (a, b) becomes (-a, b).
