This lesson is part of my Quadratic Functions Unit
This lesson includes 2 pages of guided notes and a 1 page assignment.
Students learn about the discriminant in the order below. They will:
- Solve 3 quadratic equations, indicate how many solutions they have, and relate that to the zeros of the functions they define
- Discover the discriminant and the information it gives us
- Find the discriminant for quadratic equations and indicate the number of roots each has
- Look at the graphs of functions to decide whether their discriminants are positive, negative, or zero
Answer key is included!
