**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.

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 #16**The expression 150 (1.02

^{h}) 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.
