    You can answer that yourself. If you have a positive number and you square it will the result be positive or negative?

    no the equation would probably be reflected that doesn't mean it goes up or down

    for any value of x, (x-2)^2 will always be positive correct?, or if x = 2, it will be 0.

    wait im getting a photo of how it looks like but if you have a ti-84 calculator go to y= then go to the button where it has "x,t,o w/ a slash in a middle, n" which is located right next to the alpha button then go to the x squared then press graph

    okay katie, it is very simple. at x = 2, y = 0. for all other values of x, y is negative. correct?

    Because any number squared will be positive, and any positive number multiplied by -1 will be negative.

    so you will have an inverted parabola with its vertex at x = 2
