Answer:

C

Explanation:

The function of table A can be written as ...

y = 100x -92

__

The function of table B can be written as ...

y = 10x +446

__

The function of table C can be written as ...

y = (5/3)·3^x

__

The function of table D can be written as ...

y = 2x +413

__

The exponential function of Table C will have the largest y-values for any value of x greater than 6.

_____

Comment on the functions

When trying to determine the nature of the function, it is often useful to look at the differences of the y-values for consecutive x-values. Here, the first-differences are constant for all tables except C. That means functions A, B, D are linear functions.

If the first differences are not constant, one can look at second differences and at ratios. For table C, we notice that each y-value is 3 times the previous one. That constant ratio means the function is exponential, hence will grow faster than any linear function.
