Exponential Growth

Today in class we finished up the problem we started yesturday, The Kingdom of Monterak. We also started problem 2.1 in the Growing, Growing, Growing book. Both these problems have to do with exponential growth. Exponential growth is based on the growth factor.

The growth factor-
-the fixed number of increase (ex. doubling, tripling)
-the base in the equation (see below)
-the ratio of change from one y value to the next.

When you do these kind of problems, you should use an equation like this.

y=a(b)[to the x power]

The y is the dependant variable.
The x is the independent variable. (the exponent)
The a is the initial value. (the y-intercept)
The b is the growth factor.
