1. Plot the following points by hand or using an online graphing calculator. What is the function that best fits the points?

Zigmanuir [339]

Exponential. This is an exponential function since it’s being multiplied by a constant rate. That rate is 2. The y axis is constantly being multiplied by 2. 3*2 is 6, 6*2 is 12, 12*2 is 24.
