CSU Global Campus Real World Applications & Logarithmic Relations Worksheet

Your task for this discussion is as follows:

1.Find or create a data set that represents an exponential relation.

2.Discuss how you determined Part 1.

3.Find or create a data set that represents a logarithmic relation.

4.Discuss how you determined Part 3.

5.In your responses to peers, compare and contrast your examples with others and reflect on your peers’ examples.(see attached peers)

Hello everybody,
For my exponential relation I had the following:
Population Growth 1900-1980
400000
350000
300000
250000
200000
150000
100000
50000
0
1880
1900
1920
1940
1960
1980
2000
This data represents the population growth in my from 1900 to 1980. It shows that for a while, from about 1900 to 1940, there wasn’t a large amount
of growth but once it hit after that, we started to increase in population, and it hasn’t slowed down since.
For my logarithmic relation I had this:
Population Growth 2010 – 2013
19700
19600
19500
19400
19300
19200
19100
19000
18900
2009.5 2010 2010.5
2011
20115
2012
2012.5 2013 2013.5
This data represents the population growth in my city, from 2010 to 2013. It was the easiest data to collect for logarithmic relation and does a good
job showing it in on graph. My city has done a lot of growing in the past few years, so post 2013 the graph starts to take the look of an exponential
relation.
Hello Class,
Exponential Relation:
30000
90000
60000
30000
Number of Bacteria 00
40000
30000
20000
10000
LE
0 30 60 90 120 130 180 210 240
Time
This function increases over time, skyrockets around 120t. It seems that the number of bacteria will continue to increase as time goes on. I determined
that this is an exponential relation.
Logarithmic Relation:

Time Chours)
This was determined to be a logarithmic relation by noticing the shape of the graph. In Inbetween 10 hours and 35 hours.
