Evidence Statement Text:

Interpret exponential expressions, including related numerical expressions that represent a quantity in terms of its context.★
Interpret parts of an expression, such as terms, factors, and coefficients. Interpret complicated expressions by viewing one or more of their parts as a single entity. For example, interpret P(1+r)n as the product of P and a factor not depending on P.

1. EOY Released Test Item 11
One day an e-mail is sent to 7 people. That day each person who receives the e-mail sends the e-mail to two friends. Each friend who receives the e-mail sends it to two more people on the following day. Consider an expression used to determine the number of people who receive the email on day n, if the pattern continues. Parts of the expression are shown. Interpret the meaning of each part of the expression by dragging it to the appropriate box. (Not all parts will be used.) Identify parts of the expression into the appropriate boxes.
2. Paper Test, Unit 2, Item 21
Elephant Population Estimates - Namibia
Combined estimates for Etosha National Park and the Northwestern Population
The elephant population in the northwestern Namibia and Etosha National Park can be predicted by the expression 2,649 (1.045)b, where b is the number of years since 1995. What does the value 2,649 represent?
A. the predicted increase in the number of elephants in the region each year
B. the predicted number of elephants in the region in 1995
C. the year when the elephant population is predicted to stop increasing
D. the percentage the elephant population is predicted to increase each year

3. 2016 #16The expression 150 (1.02h) represents the number of bacteria in a laboratory experiment at time h, in hours. Which parts of the expression correspond to the number of bacteria at the start of the experiment, the hourly rate of growth, and the number of bacteria when h =1 ? Identify the parts into the corresponding box. Not all the parts will be used.
