We begin by restating the question and the provided data to ensure we’re evaluating the right information.
Question and data: Determine whether the table-based function is linear, exponential, or neither. The table shows pairs (x, f(x)) as follows: x = -1 -> f(x) = 9/8, x = 0 -> f(x) = 9, x = 1 -> f(x) = 72, x = 2 -> f(x) = 576, x = 3 -> f(x) = 4608. The task also asks us to give a model if it’s linear or exponential.
Option A states: The function is exponential. An exponential function that models the data is f(x) = 9·8^x.
Option B states: The function is linear. A linear function that models the data is f(x) = [input].
Option C states: The function is neither linear nor exponential.

Analysis of each option:
- Option A (exponential with f(x) = 9·8^x):
  Let’s test the exponential pattern by looking at successive values. Starting from x = 0 to x = 1, f(1) = 72 and f(0) = 9, which is a factor of 8: 72 ÷ 9 = 8. From x = 1 to x = 2, f(2) = 576 and f(1) = 72, which again is a factor of 8: 576 ÷ 72 = 8. From x = 2 to x = 3, f(3) = 4608 and f(2) = 576, giving 4608 ÷ 576 = 8. Even at x = -1, f(-1) = 9/8, and f(0) = 9, giving 9 ÷ (9/8) = 8. The consistent multiplicative factor of 8 between consecutive x-values is a hallmark of exponential growth with base 8, and the explicit form f(x) = 9·8^x matches all the given values. Therefore, Option A is consistent with an exponential model.
- Option B (linear):
  If the function were linear, differences f(x+1) − f(x) should be constant for all x. Compute a few differences: f(0) − f(-1) = 9 − 9/8 = 63/8 ≈ 7.875. Next, f(1) − f(0) = 72 − 9 = 63. Then f(2) − f(1) = 576 − 72 = 504, and f(3) − f(2) = 4608 − 576 = 4032. The successive differences are not constant; they increase dramatically, which contradicts linear behavior. Thus, the data do not fit a linear model.
- Option C (neither linear nor exponential):
  Since we observed a constant multiplicative factor between successive f(x) values (each step multiplies by 8), the data align with an exponential pattern rather than a neither case. Therefore, claiming it’s neither would be incorrect given the observed ratio consistency.

In summary, Option A’s characterization of the data as exponential with f(x) = 9·8^x aligns with the ratios between consecutive f(x) values and matches all provided points, while Option B fails the linear-difference test, and Option C contradicts the clear exponential pattern observed.
