k Drawing a Parabola that Opens Vertically
A parabola with a vertical axis is one whose principal axis is parallel to the y-axis. There are
two possible equations for a parabola with a vertical axis:
y = A(x – H)
2
 + K and y = Ax
2
 + Bx +C.
u ClassPad Operation
(1) In step (2) of the procedure under “Drawing a Parabola that Opens Horizontally”, select
“Y = A(X – H)
2
 + K” or “Y = AX
2
 + BX + C”.
(2) Specify values for the coefficients.
