Does y=(x-3)2 open up or down

The parabola opens upward because it is in the form y = a(x-h)^2 + k

The value of 'a' is a = 1, which is positive. Whenever a > 0, the parabola opens upward. If a < 0, then the parabola would open downward.

total amount of money that he should pay if he has not used his duty free exemption is $98
