Question

Hello! How would I prove that the data is exponential? I tried to find a pattern but was unsuccessful. Here is the question:

21 87
22 98
23 111
24 125

Answer 1

hard to say, but since the change in y steadily increases, as do the successive differences, it's likely not polynomial. Since your values are all integers, it's tough to show that the differences are proportional to the values at each step.
