The equation provided in the image is:

$y = \frac{\sqrt{x} - 1}{\sqrt{x} + 1}$

Would you like to analyze this function further in terms of its properties such as:

• Domain
• Range
• Asymptotes
• Limits
• Derivative or Integral

Let me know how you'd like to proceed or if you have any other questions.

Here are 5 related questions that can help deepen understanding:

1. What is the domain of the function $y = \frac{\sqrt{x} - 1}{\sqrt{x} + 1}$?
2. What happens to the function as $x \to 0$?
3. How does the function behave as $x \to \infty$?
4. What is the derivative of the function with respect to $x$?
5. Are there any horizontal or vertical asymptotes for this function?

Tip: When dealing with square root functions, always check if the domain is restricted by non-negative values, since $\sqrt{x}$ is defined only for $x \geq 0$.
