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).

f(x, y) = (x, -y)
Nothing really happens. y is swapped for -y. But that is what reflection means and so is a tautological answer!
True :)
if you have a square acre how many ft. across is it
side across from 30: 1/2 the hypontenuse side across from 60: the length of the side across from 30, times the square root of 3 side across from 90: the hypotenuse
