Read each question carefully and answer to the best of your ability. Show all your work for short answer questions.

1. A company's profit (P) in thousands of dollars over 't' months is modeled by the function P(t) = -0.5t² + 10t - 20. At what month does the company reach its maximum profit?

a

5 months

b

10 months

c

15 months

d

20 months

2. The population growth of a city is modeled by an exponential function. If the initial population was 100,000 and it doubled in 20 years, which graph would best represent this growth?

a

Linear increasing graph

b

Exponential increasing graph

c

Linear decreasing graph

d

Exponential decreasing graph

3. The   of a graph represents the rate of change between two variables.

4. A graph showing the relationship between distance and time for an object moving at a constant speed would be a   line.

5. A scientist is tracking the decay of a radioactive substance. The half-life is 5 years. If she starts with 100 grams, sketch a graph showing the amount of substance remaining over 20 years. Label your axes.
