Unit 4 - Applications of Quadratics
Now that we know what a quadratic relationship is and how they look (parabolas), we can start working with the algebra more to solve problems and connect to real-life scenarios.
Heads-up, this is a shorter unit with only 5 lessons but they are more difficult in nature!! Attendance and practice are crucial. Also, we have the mock literacy test between some lessons. Check your cohort calendar!
