Day 1 Spring Semester

Algebra 2H pd 1

After reviewing the expectations for this semester, we started an exponential function problem.
What happens by the 30th day of a month if you begin with 1 cent on day 1, 2 cents on day 2, 4 cents on day 3, and so on until day 30?
How much will you receive on day 30? How is this answer related to powers of 2?

HW Finish the chart we started in class today, and go over the class expectations with your parents making sure they sign on the back with their daytime phone number and e-mail address, if possible.
EC problem......Describe the nature of an exponential function using 2^x as your example. Make a chart and graph your ordered pairs.

Geometry H pds 2,4
After going over the class expectations for the spring semester, we reviewed the concept of ratios, completing a puzzle worksheet during class. A ratio is a comparison of 2 numbers in the same unit of measure.
HW Do the puzzle worksheet handed out at the end of today's class. Also, have your parents sign the paper on class expectations. Make sure they write their daytime phone number and e-mail address if possible.
EC What is the ratio of 10 inches to 4 feet?

Algebra 2B pd 5
After reviewing the expectations for the spring semester, we went over a problem related to exponential functions.
How much money would you receive at the end of 30 days if you received 1 cent on day 1, 2 cents on day 2, 4 cents on day 3, 8 cents on day 4, and so on until the end of the month? The answer surprised many of you. We then went over the function y = 2^x where x = the exponent. We will continue with exponential functions tomorrow.
HW Have your parents sign the paper on the class expections for this semester. Make sure they include a daytime phone number and e-mail address if possible.

EC problem.....Why do you think exponential functions start out with slow growth, and then increase so quickly towards infinity? Answer in at least two sentences.
