Today we talked about quadratics some more, and specifically focused on how to find the equation if given only the graph. You should now be able to also apply these concepts to a word problem.

Tonight for homework you must determine the equation (a quadratic) representing the St. Louis Arch using the picture provided in class. Use our word problems from class to help you set up the equation.

Have a great night!

Coming up:
