2/26 Algebra 1 - Negative Exponents and Division Rules

We continued our work with exponents today, the new rules we learned applied to zero, negative and division of exponents. Students took notes over our new rules and some example problems. They began work on the assignment towards the end of class. Here is a good page showing all the rules we have covered so far. The video above also explains the negative exponents we talked about today in class.

Homework:
page 459 #'s 14-44 even & page 466 #'s 20-48 even

2/26 Algebra 2 - Intro to Exponential Growth

Today students were introduced to the concept of exponential growth. You can see an exponential growth function graphed in the video above. Students were also shown how to solve word problems involving exponential growth and compounding interest.

Homework:
p. 469 #'s 13-24 all, 26-42 (list y-intercept, asymptote, and increasing/decreasing only), 45,48,52,59-64,66b

If you don't have a calculator handy, here is an internet exponent calculator.
