STEP 2: Calculate the difference in the x- and the y-values

As the independent variable x changes by a constant amount, the dependent variable y is multiplied by a constant factor, which means consecutive y-values form a constant ratio.

As the x values increase by 1 the y values are multiplied by 2. So, this is an exponential function.
