Question
**Problem Statement:**

Use the figures to evaluate the function if \( f(x) = \tan x \).

Evaluate \( f(\alpha + \beta) \).

(Simplify your answer. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression.)

**Diagrams Explanation:**

1. **First Diagram**:

   - Represents a circle with the equation \( x^2 + y^2 = 4 \).
   - An angle \( \alpha \) is shown in standard position, with its terminal side intersecting the circle. 
   - The intersection point on the circle is labeled as \( (x, -1) \).

2. **Second Diagram**:

   - Represents a circle with the equation \( x^2 + y^2 = 1 \).
   - An angle \( \beta \) is shown in standard position, with its terminal side intersecting the circle.
   - The intersection point on the circle is labeled as \( \left( \frac{1}{3}, y \right) \).

**Objective:**

Calculate the exact value of \( f(\alpha + \beta) \) using the given information from both diagrams.
