Which of the following correctly describes the graph of an exponential function with a base of three?

An exponential funtion is graphed on the figure below to model some data that shows exponential decay. At , is at half of its initial value (value when ). Find the exponential equation of the form that fits the data in the graph, i.e. find the constants and .

Give the -intercept of the graph of the equation .

What is/are the asymptote(s) of the graph of the function ?
