# Activity One

The table below shows song bites from 4 different songs to be used for the 5-minute mashup. First, graph the beats per minute (BPM) as a function of time. Then find the piecewise function for the graph.

# Activity Two

Determine the tempo for 0 < x < 3 by finding the average BPM for all sound bites.What is the average? Round your answer to the nearest whole number.

**Answer: 122, 0 < x < 3**

Graph the finished mashup.

Write a function that represents the graph.

What are the BPM when the song reaches 3.5 minutes? 4 minutes? 5 minutes?

**Answer: 3.5 minutes = 123 BPM, 4 minutes = 126 BPM, 5 minutes = 146 BPM**

# Activity Three

**Songs: **

**Careless Whisper by Seether: 134 BPM**

**Right Here by Staind: 112 BPM**

**Never Too Late by Three Days Grace: 150 BPM**

**Angel by Theory of a Deadman: 152 BPM**
