To solve the problem of finding \( f(3) \) from the graph:

- The graph contains two functions: \( y = f(x) \) (a sinusoidal curve) and \( y = g(x) \) (a straight line).
- The question asks for \( f(3) \), which means we need to find the y-value of the function \( f(x) \) when \( x = 3 \).

### Steps:
1. Locate \( x = 3 \) on the x-axis.
2. From that point, trace vertically until you intersect the curve representing \( f(x) \) (the sinusoidal curve).
3. At \( x = 3 \), the corresponding y-value on the \( f(x) \) curve is approximately \( -2 \).

Thus, \( f(3) = -2 \).

### The correct answer is D: \(-2\).
