In this activity, you are going to use your knowledge of quadratic functions to model using them.
Find two quadratic functions that pass through these points. You may use the input box to check your answers.
The "Ponte da Ribeira d'Ametade" is a car bridge in Madeira Island built in the 1940s by João Augusto de Sousa. It has stayed true to its original design and is highly shareable on social media. It can hold a lot of weight due to its parabolic arch. We have superimposed a picture of it on the cartesian plane.
Find a quadratic function that models the arch of the bridge
In the next image, you have a long jump separated into freeze frames.
Find the curve which describes the trajectory of this jump.
Find a function which models this hanging necklace. Try two models.
