c) Write down the linear model's equation and describe what each of the items in the model
mean in "real-world dice rolling terms".
d) Write down the exponential modeľ's equation and describe what the positive value in the
model means in "real-world dice rolling terms".
e) How come the exponent is negative?
f) Where is the initial value in the linear model?
B) Where is the initial value in the exponential model?
h) Where is the rate in the linear model?
i)
Where is the rate in the exponential model?
Which is a better model for this data? How can you determine this by looking at the chart of
the data?
