When you reflect around the x-axis, the sign of every y-coordinate changes.
If the point started out above the x-axis, it flips under ... positive 'y' becomes negative.
If it started out under the x-axis, it flips above ... negative 'y' becomes positive.

How do you reflect over the x axis when a point is over the x axis already?
To reflect a point in the x axis, multiply it's y coordinate by -1. Example: (x, y) over the x axis is now (x, -y), If you come across the y already being a negative, then make it a positive, (x, -y) = (x, y). The x stays the same, and vice versa over the y axis. Hope I helped. I am also having trouble with this, though, What if there is a zero? (5,0), it can't be (5, -0) can it?
How do you reflect over x axis?
You change the value of y to -y. ex: (4,5) reflected over the x-axis is (4,-5)
Which sequence of transformations will result in an image that maps onto itself?
reflect across the x-axis and then reflect again over the x-axis
What reflects across the x-axis?
If a function reflects along the x-axis, that indicates that it has both negative and positive solutions. For example, y = x2 reflects along the x-axis because x2 = -x2. In general, a function will reflect along the x-axis if f(x) = f(-x).
Is the x coordinate of a point that lies on the x-axis negative?
If it is on the X-axis, the the value of x is zero so it is not negative.
How do you reflect over the y axis when your x axis is already negative?
The bit with the negative x-axis goes to the positive x-axis.
How do you reflect over x axis if the points are negative?
same as if they were positive
How do you reflect figures over x axis?
no

How do you reflect a traingle over the x axis?
by looking and controling it

How do you reflect an image over the X-Axis?
change the y value to -y, and bring the negative over the equal sign. example. y=2x^2 reflected on the x-axis looks like y=(2x^2)/-1 which is equal to y=-(2x^2)
What reflects across the x-axis?
If a function reflects along the x-axis, that indicates that it has both negative and positive solutions. For example, y = x2 reflects along the x-axis because x2 = -x2. In general, a function will reflect along the x-axis if f(x) = f(-x).
Multiplying by a negative number flips the graph of a function over the -axis?
x
Is the x coordinate of a point that lies on the x-axis negative?
If it is on the X-axis, the the value of x is zero so it is not negative.
What does Rx0 mean?
If it is Rx=0, it means you are reflecting your set of coordinates and reflect it across the x-axis when x=0. So it pretty much is saying reflect it over the y-axi
