My function is bigger than your function. I’m pretty sure it is safe to say the magnitude of functions is very rarely the topic of a sibling or lovers quarrel, but if the subject did arise it would be extremely helpful to know how to compare functions.
Comparing Functions begins by re introducing students to the concept of finding slope that they have learned in previous lessons. From there students use this concept to compare functions using the slope in various forms. Using situations that students are familiar with, such as text messaging and cake, they apply their understanding of comparing functions to solve a variety of problems.
