How can you use a table, a graph, and an equation that represent an exponential function to find the y intercept and growth factor for the function?...

Minor
addition to the answer:

Finding Growth Factor from the graph:

From the graph `y_1=6, y_2=12, y_3=24`

Growth
factor(b)=`y_2/y_1=y_3/y_2`

Growth factor=`12/6=24/12=2`

So, Growth Factor will be constant.
