Same y‐intercept.  When x=0, y=1 for all functions.asymptote

Where the function crosses the y‐axis. To find the y‐intercept, you must set x=0.

A line that a curve approaches more and more closely, but never touches. 

If the Base > 1, the graph is increasing.  If  0 < Base < 1,the graph is decreasing.

Learning Goal:

I will learn how to graph exponential equations. 

Success Criteria:

To be successful, I must be able to...

• Graph an exponential function using a table of values

• Identify the y‐intercept (when x=0) and the asymptote

• Identify whether the function is increasing or decreasing
