What s the domain of y x 2. We know that any. The range is the set of all valid values. 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. Thus the domain is all real numbers or from infinity to infinity.
According to the definition a point in a region r is a boundary point if it is the center of every disk that contains points that lie outside of r as well as. Then y sqrt 4 0 2 2 so the function is defined on 2 2. By using this website you agree to our cookie policy. This website uses cookies to ensure you get the best experience on our website.
This means that. Thus the graph of y sqrt 4 x 2 is a semicircle with radius 2 and domain. The range on the other hand is different. Free functions domain calculator find functions domain step by step this website uses cookies to ensure you get the best experience.
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. The range is the set of all valid values. Use the graph.
Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. 2 2 start by solving the equation 4 x 2 0 then 2 x 2 x 0 x 2 now select a test point let it be x 0. Let s assume you had the graph of a parabola y x 2. Use the graph.
You know that for every x you substitute there d always be a value for y. In this case there is no real number that makes the expression undefined. The domain of the expression is all real numbers except where the expression is undefined.
