identify the domain and range of each then sketch the graph 

**Graphs of Inverse Trigonometric Functions**

The image features graphs of two inverse trigonometric functions. Below is a detailed description of each graph provided for educational purposes.

**Graph 1: \( y = \sec^{-1}(x + 1) \)**

- **Axes:** The horizontal axis is labeled as \( x \), and the vertical axis is labeled as \( y \).
- **Grid:** Both axes are marked with grid lines. The \( x \)-axis ranges from -6 to 6, and the \( y \)-axis ranges from \(-\frac{3\pi}{2}\) to \(\frac{3\pi}{2}\).
- **Scale:** The vertical axis is marked with increments of \(\frac{\pi}{2}\).
- **Graph Characteristics:** This graph represents the inverse secant function with a horizontal shift. The function is typically defined for \( x \geq 1 \) or \( x \leq -1 \), and it reflects periodic discontinuities typical of secant functions.

**Graph 2: \( y = \sin^{-1}\left(\frac{x}{3}\right) \)**

- **Axes:** The horizontal axis is labeled as \( x \), and the vertical axis is labeled as \( y \).
- **Grid:** Similar to the first graph, the \( x \)-axis ranges from -6 to 6, and the \( y \)-axis ranges from \(-\frac{3\pi}{2}\) to \(\frac{3\pi}{2}\).
- **Scale:** The vertical axis is also marked with increments of \(\frac{\pi}{2}\).
- **Graph Characteristics:** This graph represents the inverse sine function modified by a horizontal scaling factor. The typical domain for \( \sin^{-1}(x) \) is \([-1, 1]\), but due to the scaling, the domain here would be \([-3, 3]\).

These graphs demonstrate the behavior and transformation of inverse trigonometric functions, useful in understanding their applications in various fields, including physics and engineering.
