What Is The Domain Of Y X 2 9

Assuming we are limited to real numbers.

What is the domain of y x 2 9. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. The domain of this equation is valid except at x 9. This website uses cookies to ensure you get the best experience on our website.

The domain is all values of that make the expression defined. Range of values that can be substituted for x in a function in this case x needs to have an existing square to be part of the domain of the function y x 2 any number can be squared including positive and negative numbers and pi. X 3 or x 3 y inrr y 0 for the domain we require x 2 9 0 rarrx 2 9 rarrx 3 or x 3 domain is oo 3 uu 3 oo range is y inrr y 0 graph sqrt x 2 9.

The domain of the expression is all real numbers except where the expression is undefined. In this case there is no real number that makes the expression undefined. Determine the domain and range.

In this case there is no real number that makes the expression undefined. Yin 9 oo y x 2 9 is defined for all real values of x actually it is defined for all complex values of x but let s not worry about that. The domain of the expression is all real numbers except where the expression is undefined.

The range is the set of all valid values. The range of an even indexed radical starts at its starting point and extends to infinity. By using this website you agree to our cookie policy.

If we are restricted to real values then x 2 0 which implies x 2. The range is all real values of y except 0 since y can approach 0 but will never actually be 0. This means that.
