Example 2

The bacteria Streptococcus lactis doubles every 26 minutes in milk. If a container of milk has 4 bacteria in it to start, write an equation that models this scenario and then graph the equation.
  1. Read the problem statement and then reread the scenario, identifying the known quantities.
  2. Substitute the known quantities into the general form of the exponential equation .
  3. Create a table of values using the resulting equation.
  4. Set up the coordinate plane.
  5. Plot the points on the coordinate plane and connect the points with a curve.
