we are asked in the problem to determine the exponential function that best fits to the data points : {(1, 4), (2, 12), (3, 32), (4, 60)} We can use an online tool or MS Excel to plot the data and then get the exponential trendline. The general form of exponential function is y = ax^n. Based on the tools used, the equation is Y = 2.252(1.485^X)
