Lesson 2.4: Quadratic Functions and the Real World

Businesses that sell products or services aim to set pricing that will optimize their profits. If a price is lowered, the business may sell more items/services, but will make less profit for each item/service sold. If the price is increased, the business will make a great profit for each item/service sold, but may sell fewer items/services. A quadratic function can often be used to represent these price optimization scenarios, as well as many others. This lesson will focus on some possible scenarios.


In Lesson 2.4, you will learn about

  • solving problems that can be modelled by quadratic functions and solved using skills you learned in Lessons 2.1, 2.2, and 2.3
