To determine which function is nonlinear, we can look at the equations provided:

1. \( y = 5.2 (7.1)^x \) - This is an exponential function because of the variable \( x \) being in the exponent.

2. \( y = \frac{5}{8} x \) - This is a linear function in the form of \( y = mx + b \).

3. \( y = 8 \cdot 2^{x - 9} \) - This is also an exponential function due to the variable \( x \) in the exponent.

4. \( y = 12x + 8 \) - This is a linear function in the form of \( y = mx + b \).

Based on these observations, the nonlinear functions are:

- \( y = 5.2 (7.1)^x \)
- \( y = 8 \cdot 2^{x - 9} \)

Thus, both options 1 and 3 are nonlinear. If you are looking for a single answer, you might want to select the first option provided:

**\( y = 5.2 (7.1)^x \)** (or alternatively, you could consider the one that is presented first in the list).
