Hello, I am really struggling on question #23. I can't seem to find the appropriate Exponential Function that best fits this data.

The general formula is f(x) = a * b ^ x , where a is the first term, b is a the growth factor and x is the variable.

Let x represent time after 1950.

If a = 132 459

f(x) = 253 539

x = 20? //This part I am not sure about

So my attempt would look like this:

253 539 = 132 459 ( b ) ^ 20

b = 1.03299

However, f(x) = 132 459 ( 1.03299 ) does not satisfy the year at 1994, x = 44.

Where did I go wrong?
