**Text:**

Use the graph to determine the value of each composite function.

\((h \circ f)(3) =\)

\((f \circ g)(4) =\)

---

**Graphs and Diagrams Explanation:**

The image contains three graphs labeled \(h(x)\), \(g(x)\), and \(f(x)\):

1. **Graph of \(h(x)\):**
   - This graph appears in the upper left quadrant.
   - \(h(x)\) shows a parabolic shape, opening upwards. It is plotted on a standard Cartesian plane with x-values ranging from approximately \(-5\) to \(5\), and y-values from \(0\) to \(5\).

2. **Graph of \(g(x)\):**
   - Located in the upper right quadrant.
   - \(g(x)\) resembles a wave pattern with peaks and valleys, indicating periodic behavior. The function has visible oscillations within the same x-values range \([-5, 5]\) and y-values from \(0\) to about \(5\).

3. **Graph of \(f(x)\):**
   - This graph is in the lower quadrant, underneath \(h(x)\) and \(g(x)\).
   - \(f(x)\) is represented as a straight line. It spans all four quadrants, forming a diagonal through the origin suggesting a linear function.

**To solve for the composite functions:**

- **\((h \circ f)(3)\):**
  Evaluate \(f(3)\) using the line graph, then apply the result to \(h(x)\) on its curve.

- **\((f \circ g)(4)\):**
  Determine \(g(4)\) using the wave pattern, then use this result to find \(f(x)\) in the line graph.

This exercise demonstrates how to evaluate composite functions by analyzing graphical data efficiently.
