Quadratic polynomial function is a function of the second degree. The quadratic function has the form:
F(x) = y = a + bx + cx2
where a, b, and c are numerical constants and c is not equal to zero.
Note that if c were zero, the function would be linear.
A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero.The graph of a quadratic function is a curve called a parabola. Parabolas may open upward or downward and vary in "width" or "steepness", but they all have the same basic "U" shape. The picture below shows three graphs, and they are all parabolas.
Students compared the various graphics functions and square commented vihove differences and characteristics. They used a drawing program: https://rechneronline.de/function-graphs/

Characteristics of quadratic function we studied using Geogebra .
With Phet interactive simulation Projectile motion, students learn about projectile motion by firing various objects. They can set the angle, initial speed, and mass, add air resistance. What more, they can make a game out of this simulation by trying to hit a target.
What we want to achieve by using simulation?
- Predict how varying initial conditions affect a projectile path(various objects, angles, initial speed, mass, diameter, initial height, with and without air resistance).
- Use reasoning to explain the predictions.
- Explain common projectile motion terms in their own words. (launch angle, initial speed, initial height, range, final height, time).
- Describe why using the simulation is a good method for studying projectiles.

How the graph quadratic function can be used in forensics and what is forensic ballistic, students explained forensic from Serbian national forensic crime center.
This lecture helped us to find out:
A projectile is any object projected into space (empty or not) by the exertion of a force. The term projectile most commonly refers to a ranged weapon. Mathematical equations of motion are used to analyze projectile trajectory.
Forensic ballistics involves analysis of bullets and bullet impacts to determine information of use to a court or other part of a legal system. Separately from ballistics information, firearm and tool mark examinations involve analyzing firearm, ammunition, and tool mark evidence in order to establish whether a certain firearm or tool was used in the commission of a crime.
