The plot of the data in the table is shown below.

And the plot of the answer choices is plotted in the following figure.

As we can clearly see, the exponential function of choice D best fits the data in the table,

Hence, choice D is the correct one.

A)y= 160.5 (2.3^x) + 20.5B)y= 99.8 (1.5^x) - 80.8C)y= 120.4 (0.8^x) – 209.1D)y= 147.3 (1.2^x-example-1
