To determine which function is nonlinear, let's analyze each of the given functions:
1. **\( y = 8 \cdot 2^x - 9 \)**: This function involves an exponential term \( 2^x \), which makes it nonlinear.
2. **\( y = 5.2 \cdot (7.1)^x \)**: Similar to the first function, this one also has an exponential term \( (7.1)^x \), indicating that it is also nonlinear.
3. **\( y = 12x + 8 \)**: This is a linear function; it follows the form of a linear equation \( y = mx + b \).
4. **\( y = 58x \)**: This function is also linear, in the form \( y = mx \).
Based on this analysis, the nonlinear functions are:
- **\( y = 8 \cdot 2^x - 9 \)**
- **\( y = 5.2 \cdot (7.1)^x \)**
Therefore, the functions that are nonlinear are the first and second ones.
