Pre-Calculus
Exponential Growth and Decay Project
Information Sheet
Name ____________________________ Pd ____
1) Topic: _________________________________________
2) Research your topic and find at least 5 data points (more would be even better!) demonstrating the
exponential growth or decay of your topic. Create a table that displays the data and attach a copy of the
source where you found these data points.
3) Find an exponential regression equation that models the growth/decay of your data points. Round to the
thousandths place.
4) Graph your data points AND the regression equation on the graph below. Make sure to label your axes.
5) Use your regression equation to predict…
a) The state of your topic in 10 years (2023)
b) When your topic will reach a certain value. (Ex. When
will MySpace have less than 1 million users)
Exponential Growth and Decay Presentation
After you have researched your topic and completed the information sheet, you will prepare a
3-4 minute presentation to share your findings with the class. Your presentation will be graded
using the following rubric.

Introduction
Introduction stimulates
attention (Ex. audience
participation) and focuses
on the topic.
Introduction gains attention
and relates to the topic.
Introduction does not
stimulate attention and
lacks focus.
History
Presenter provides a
thorough history of the
topic that includes the
reason for the exponential
growth or decay
Presenter provides a
detailed history of the topic,
but does not discuss the
reason for the exponential
growth or decay.
Presenter gives a basic
description of the history of
the topic, leaving out a lot
of important aspects,
including the reason for
exponential growth or
decay.
The data and regression
equation are displayed in a
way that clearly
demonstrates the
relationship between them
and the exponential
growth/ decay of the topic
Presenter uses the
regression equation to
make a prediction about
the future. The presenter
also demonstrates how
he/she arrived at this
prediction and describes
how realistic the prediction
is.
The visual aid is neat,
organized, creative, and
beneficial to the overall
presentation.
The presenter is wellrehearsed, has good eye
contact, and demonstrates
confidence.
The data and regression
equation are displayed in a
way that clearly
demonstrates the
relationship between them
or the exponential
growth/decay of the topic
The data and regression
equation are displayed, but
it is difficult to see the
relationship between them
and the exponential
growth/decay of the topic.
Presenter uses the
regression equation to
make a prediction about
the future. The presenter
also demonstrates how
he/she arrived at this
prediction or describes how
realistic the prediction is.
Presenter uses the
regression equation to
make a prediction about
the future, but does not
demonstrate how he/she
arrived at this prediction or
describe how realistic the
prediction is.
The visual aid is neat and
organized, but it presents
the information in a generic
way.
The visual aid was not neat
or organized in showing the
necessary information.
The presenter
demonstrates two of the
three qualities described.
The presenter
demonstrates one of the
three qualities described.
