Let’s see if anyone bit at my extra credit. Not that difficult, watch/listen to/read some election coverage. Look for the “margin of error” when they predict the winner. Make an absolute value inequality, solve it, and graph it. I announced it on the 3rd, and people seemed like they were going to do it, but we’ll see. And they seemed sort of involved when I said my piece – “See? This extra credit has nothing to do with a job. But the point is you CAN describe it algebraically. And, when there are reports and studies, things often-times ARE described algebraically. It takes a lot less space on a page to write |x-54|<3 than it does ‘We think he’s got 54% of the vote, but it could be within 3% either way’.” Someone was standing in the way of the projector. I stopped, put tape on the floor, and said “now look, the light travels in a V-shape towards the screen, correct? Well, if the bulb is the origin, and we use the floor tiles as a coordinate plane, what is the absolute value function of the light?” Maybe they like making random math problems about random things better than trying to relate to an occupation or interest that probably 1 or 2 of them have…everyone can see the projector light. Not everyone likes baseball.
