Reflecting over a diagonal line is only a bit more complicated, as it involves rotation of the frame of reference. In this case, the x-variable is the one being transformed. But what would happen if instead of it just being the square root of x, what would happen if we Then we need to move to the left by that amount. Let's try a harder example to drive this point home. B is two units above the X axis. Now, how would I flip it over the x-axis? so how did you get 1/4? This is what flips it over the x-axis, and then multiplying it by this fraction that has an absolute value less than one, this is actually stretching it wider.
