R(3) in context...
It rained 3 days and 3 nights and caused a great flood
3 hours and the cake is ready
Amount in rain gauge after 3 hours
R(.5)=14
There were 14 mm of water in the gauge after half an hour of rain.
There was a half mm of water in the rain gauge after it rained for 14 hours
Raining for half an hour equaled the rain of raining for 14 minutes.
Half a drop of rain makes 14 daisies
Using function notation...
R(t)=6
R(6)=t
R(6)=37
R(37)=6
Using function notation...Make sure to reread the definition of the variables. That will help eliminate some answers.
R(1.5)=90
R(1.5)=R(2)
R(90)=2
R(2)=90

Now as a function. If you figured out #13 correctly, this is just putting that infor into function notation. Or use these choices here to help you think about #13 better.
r(w)=75
r(w)=75-w
r(w)=75-4.5w
rate of growth in millions
.52 million per year
2.6 million per year
5 million per year
