## Reflect on the concept of polynomial and rational functions. What

Question Reflect on the concept of polynomial and rational functions. What concepts (only the names) did you need to accommodate these concepts in your mind? What are the simplest polynomial and rational function you can imagine? In your day to day, is there any occurring fact that can be interpreted as polynomial and rational functions? What strategy are you using to get the graph of polynomial and rational functions?

## A college radio station surveyed incoming freshmen to gather information

Question A college radio station surveyed incoming freshmen to gather information about the types of music that they like. Here are the results. -688 incoming freshmen were surveyed in all -323 of the freshmen like jazz -304 of the freshmen like classical -119 of the freshmen like both classical and jazz -197 of the freshmen like both classical and rock -221 of the freshmen like both jazz and rock -88 of the freshmen like all three types of music (classical, jazz, rock) -126 of the freshmen don’t like any of these three types of music (classical, jazz, rock)Construct a Venn diagram illustrating these results. Then answer the question.How many of the freshmen like classical, but like neither jazz nor rock? ____ freshmen

## Tom is standing 7 feet west and 50 feet north of a radio playing

Question Tom is standing 7 feet west and 50 feet north of a radio playing Music, which can be heard in a radius of 25 feet. he heads south at 4 feet per second, but after traveling 35 feet, he cannot bear the sound any longer and turns east. he then travels east at 3 feet per second until he can no longer hear the radio. How long can tom hear the music? (In other words, how long is she within 25 feet of the radio?)
