because "h" moves the graph left and right and "k" moves it up and down. so you take the origanal graph "y=x^2" then move it -h L or R and k up or down.

It's not wrong to plot points to graph the equation you gave, it's just unnecessary. The equation is written in a form to give you the information you need to sketch it without plugging in points. The parabola in question (assuming a<>0) has a vertex at (h,k). If a>0, it opens upward; for a<0, downward. The magnitude of a will determine how wide or narrow the parabola is; for instance a=3 or a=-3 will be narrower than a=1.

Plotting points is necessary for beginners, this is the equation of a parabola having the y-axis as its axis.

oh i remember shifting graphs. if you shift the graph the whole thing moves

here you are using numbers and not coordinates to find an answer. If you wish to plot, them x, y are your coordinates but it wont do you any good.
