To determine which function has a greater maximum, we need to compare the maximum values of the given functions \( f(x) \) and \( g(x) \).

### 1. For the function \( f(x) = -5(x + 4)^2 + 8 \):
This is a quadratic function in vertex form:  
\[ f(x) = a(x - h)^2 + k \]  
where \( a = -5 \), \( h = -4 \), and \( k = 8 \).

- The vertex of this parabola is at \( (-4, 8) \), which is the maximum point because the parabola opens downwards (since \( a = -5 \) is negative).
- Thus, the maximum value of \( f(x) \) is **8**.

### 2. For the function \( g(x) \) (from the graph):
The graph of \( g(x) \) shows a parabola that opens downward. The vertex, or the maximum point, appears to be at \( (x = -7, y = 9) \).

- So, the maximum value of \( g(x) \) is **9**.

### Conclusion:
Since \( g(x) \) has a maximum of 9 and \( f(x) \) has a maximum of 8, **\( g(x) \) has a greater maximum than \( f(x) \)**.

The correct answer is **B**: \( g \) has a greater maximum than \( f \).
