Here's the general info.I'm suppose to choose an Olympic sport that displays a parabolic projectile (picked Volleyball).Then,draw a model of the quadratic/parabolic shape of motion on a coordinate plane,keeping in mind it must be realistic(did that).After that,determine the maxima/minima (ball goes highest at 15ft in 3 seconds) and zeros of the graph (the ball hits the floor on the 4th second) and EXPLAIN the significance of each within the context of the specific sport.Then,I'm suppose to find the function of the graph.After finding the function,I'm suppose to find the zeros from the function using factoring,completing the square,and quadratic formula.The problem is I have no idea how to find those and the function itself.This is as much as I've known and done.
Here is the formula used in the parabola: f(x) = a(x - h)^2 + k
In the coordinate plane,The Y coordinates are the height and the X coordinates are the time(in seconds).By the 4th second,the ball hits the floor and height is zero.
Please someone,help me out!What is the function I'm trying to find and how do I find the zeros using factoring,completing the square,and quadratic formula??? :( Your help is appreciated!
