Guadratic Functions: Model Real Life Parabolas

This is Lebron James hitting a three pointer while on Miami Heat versus Golden State Warriors. It does not have a name. It is located in the Golden State Warriors Arena. It doesn't have a history behind it other than it going in. Something interesting about it was it was a buzzer beater in overtime to send them to another overtime match against the team. I chose it because I am a huge Lebron James fan I love him.

 

Quadratic Formula: y = -.06x^2+1.47x+6.67

Points: (0,6.67)(8.5,14.83)(20.75,11.34)(12.25,15.67)(25,5.92)(10,15.37)(5,12.52)

To get all 7 of my points my first 3 points I obtained of data from the interenet being the hight and distance of all the things I would need like height of player, height of basket, and how far away from basket. To do the vertex, I used x= -b/2a and then plugged in that value to the equation to get the y-cordinate. For the final 3 points I plugged in numbers to my calculator that made sense on being on the parabola. To get the quadratic formula I did quad reg in the calculator.

This is Kobe Bryant who is my second favorite basketball player of all time. Me being a Kid from San Diego you can imagine I hopped in many car rides headed up to Los Angeles to see him play. It does not have a name. It is located in the one and only Staples Center in Los Angeles. It's history is Kobe Bryant hitting on of the best three point shots of all time it was a step back three in Dwane Wade's Face as the times is expiring. I chose it because I love Kobe and I will always have a soft spot for him in my heart.

 

Quadratic Formula: y= -.06x^2 + 1.50x + 6.65

Points: (0,6.5)(8.5,14.92)(20.75,11.79)(12.5,15.88)(25,6.5)(10,15.5)(5,12.5)

To get the 7 points like with Lebron James I collected all of my important data off line. And to get the vertex I did the same thing on the parabola with Lebron James. Lastly to get the quadratic formula I did quad reg on the calculator.
