Question

How does changing the value of h affect the shape of a parabola? How about changing the value of k? How about changing the value of the leading coefficient, a?

Answer 1

h moves it to the right or left +h moves it left and -h moves it right
k moves it up and down +k moves it up and -k moves it down
changing the leading coefficient will make your parabola wide or narrow
but a -a will reflect it about the x axis

Answer 2

what a nice christmas gift from your instructor?
