Here is an activity to do with your class after you've talked about how to find the equation of a parabola given its graph. Give your class this image of the McDonald's logo and using a graphing software (like Desmos) get your students to recreate this logo. They will have to use straight lines and parabolas to do this. This is also a great time to talk about the domains, and how to restrict the domain of a function!
This resource contains one example of a logo along with the functions and domain restrictions required to graph it.
