What Is The Domain Of Y X 2 9

The range of an even indexed radical starts at its starting point and extends to infinity.

What is the domain of y x 2 9. This means that. The domain of this equation is valid except at x 9. 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. 9 x 2 0 x 2 9 implies x 3 this means that you have x 3 and.

The range is all real values of y except 0 since y can approach 0 but will never actually be 0. Determine the domain and range. 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 is all values of that make the expression defined.

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. Assuming we are limited to real numbers.

Use the graph. In this case there is no real number that makes the expression undefined. 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.

In other words in oerder for the function to be defined you need the expression that s under the square root to be positive. In this case there is no real number that makes the expression undefined. This website uses cookies to ensure you get the best experience on our website. The domain of the expression is all real numbers except where the expression is undefined.

Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. 3 0 in order to find the function s domain you need to take into account the fact that for real numbers you can only take the square root of a positive number. The range is the set of all valid values.
