PowerPoint media can be used to show how the quadratic function is determined, as follows:

Here’s a picture of the animation you just saw. The numbers are estimated.

In this example,, from the animation, we’ll assume person “A” is on the “0” metre line and that the x-axis passes through the players’ hands (this will simplify the calculations).

A B

←x - axis

↑ 0 – metre line

If person A is on the “0” metre line; the zeroes for this parabola are therefore… (0,0) and (6,0).

A

And the vertex is… (3,4).

Substituting these values (f(x)= 4; x = 3; s = 0; t = 6) into the zeroes or factored form f(x)=a(x – s)(x – t) gives…

f(x)=a(x – s)(x – t) gives:

4 = a(3 – 6)(3 – 0)

4 = a(-9) a =

This would mean that the football’s path represents a parabola that opens down, with a maximum vertex of (3,6) and function equation (in zeroes or factored form) of…

Now we have all the values we need for an

equation of this function

Or, in vertex form:

(This is zeroes or factored form).

Or, in vertex form:

(This is zeroes or factored form).

Finally, in standard form this is:
