Math Problem Statement

generate the square root function of y=x^2-2

Solution

The square root function of y=x22y = x^2 - 2 can be expressed as:

y=x22y = \sqrt{x^2 - 2}

This equation describes the positive square root of x22x^2 - 2. The domain of this function will only include values of xx for which x220x^2 - 2 \geq 0, meaning x2x \leq -\sqrt{2} or x2x \geq \sqrt{2}, because the expression inside the square root must be non-negative.

Would you like more details or have any specific questions?

Here are some related questions you might consider:

  1. What is the domain and range of the function y=x22y = \sqrt{x^2 - 2}?
  2. How would you graph y=x22y = \sqrt{x^2 - 2}?
  3. Can this function have any negative outputs?
  4. How do the solutions of y=x22y = \sqrt{x^2 - 2} compare to y=x22y = x^2 - 2?
  5. What is the derivative of y=x22y = \sqrt{x^2 - 2}?

Tip: Always check the domain of functions involving square roots, ensuring that the expression inside the root is non-negative for real-valued solutions.
