These examples have used the coefcient of -16 for the t
2
term. The value of that coefcient
could be different, based on conditions such as altitude. It would also be different on the
moon or another planet, and of course, if different units for distance and/or time were used.
A more general equation for the model would be h =
−

+ vt + c. This is an application of
the general quadratic y = ax
2
+ bx + c.
7. Explore the transformations of the graph of the
function y = ax
2
+ bx + c as the coefcients a, b, c
are changed.
Enter the function y1 = 1x
2
+ 0x + 0. The three
coefcients are needed, as explained later.
Set the window to Default.
