9. A person takes a 200mg medication at 8:30AM
A person takes a 200mg medication at 8:30AM. Every hour, 10% of the medication is eliminated from the body. How much medication would remain in the body at 1:30 PM?
Identify whether the function is linear/exponential growth/decay. Then, define your variables and develop a function that can be used to answer the question in context.

10. Determine whether the following situation is linear or exponential.
Explain your reasoning.

17. What vocabulary term is being described?
A sequence in which there is a
common ratio among any
two successive terms.

20. A car is purchased for $32,000 in 2010.
Unfortunately, the car depreciates
In value by about 3.5% each year.
How much would we expect the value
of the car to be in 2020?

21. Provide an example of a situation that represents linear “decay”.

22. Describe what happens to the graph of an exponential function when
the initial value (the “a” value)
is negative.

23. True or False: As the base value of an exponential
function increases, the angle of
the curve becomes steeper.

24. y-intercept, domain and range?
What is the asymptote,
y-intercept, domain and range?
