The original parabola is: f(x) = (x-h)^(2) + k

where h and k are known values and k > 0, thenoriginal parabola will have complex roots because the vertex is facing up and completely above the x-axis.

The reflected parabola has the same equation but is facing down. Therefore its equation will be: f(x)= -(x-h)^(2) + k.

Find the roots of the two equations above and compare the values of the roots for each parabola. You should be able to show that they have the same coefficients, except the original has an "extra i."

Pleaseeeee help me, it would be great if you could explain the process too!! =) Thank you so much!
