  2. Stressed Out: Slope as Rate of Change - Cynthia Lanius
    It's the night of the big game. You're in the locker room. The coach is pumping the team up. "Now, I know you people are nervous. That's okay, in fact, that's what we want. You're going to perform better on the court (stage) if you're a little nervous." Does the graph shown confirm what the coach told you? Write a statement that describes performance as stress increases... This lesson introduces basic knowledge and skills important to a study of functions in algebra and lays the groundwork for calculus. more>>
