Sketch a rough graph of the outdoor temperature as a function of time during a typical spring day.

Imagine that you are studying how the number of rabbits and chipmunks evolved between 1950 and 2000 in New York, You have collected historical data and have summarized it in the following graph: a) Find an expression for each species that helps you calculate the number of animals of each species between 1950 and 2000 as a function of the year. Use R as a symbol for rabbits, C as the symbol for chipmunks, and Y as the symbol for years. You will be finding two seperate equations.  b) For which year was the population of rabbits approximately four times the population of the chipmunks? c) There is data that supports the hypothesis that linear trends observed between 1950 and 2000 will continue in the future. By which year will both populations be approximately the same?

12. Functions that describe predator-prey relationships have periods.

Distinguish between the vertical shifts and horizontal shifts?
