Learning to graph an exponential function and identify the y-intercept

What is the significance of identifying the 'a' value in the equation y = a * B to the X?

Explain how to determine if an equation represents growth or decay based on the value of 'B'.

What values should be chosen to the left and right of the Y intercept for plotting the graph?

How do you compute the value of y when x equals -1 in the equation y = 1/3 * 2 to the negative first power?

Describe the process of finding the Y intercept and plotting points for the graph.
