Chapter 14 Math Project: Modeling Mashups

By, Truitt Briggs

Activity 1 Graph

Below is a piecewise function

y=112.6

y=112

Activity 2 Modeling

y=121+5^(x-3)

Summary:

y=a*b^(x-h)+k. y=121+5^(x-3). The b is 5 and the h is 3 and the k is

Average BPM is 122.45, rounded is 122

BPM:

At 3 minutes: 122

At 3.5 minutes: 123

At 4 minutes:126

At 4.5 minutes: 132

At 5 minutes: 146   

Activity 3:  

y=127

y=126+5^(x-3)

Below is a piecewise function

Summary:

y=126+5^(x-3) y=a*b^(x-h)+k

126=k, 5=b, 3=h

Average BPM=127

BPM:

At 3 minutes:127

At 3.5 minutes: 128.24

At 4 minuets: 131

At 4.5 minutes:137.18

At 5 minutes: 151
