What Is The Domain Of Y X 2 2

Use the graph.

What is the domain of y x 2 2. Use the graph. In this case there is no real number that makes the expression undefined. The range is the set of all valid values. The range is the set of all valid values.

The domain is all values of that make the expression defined. In this case there is no real number that makes the expression undefined. By using this website you agree to our cookie policy. The domain of the expression is all real numbers except where the expression is undefined.

But looking at the equation 2 x 1 2 3 we can tell that it is an upside down parabola shifted to the left by 1 and down by 3. 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. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. Then y sqrt 4 0 2 2 so the function is defined on 2 2.

Y 3 when attempting to find the domain and range it is best if you actually draw the diagram so you don t miss any points and when you are unsure. Locate the vertex of the parabola. The range of an even indexed radical starts at its starting point and extends to infinity. The domain of the expression is all real numbers except where the expression is undefined.

If you don t know what the graph looks like just plot a bunch of points. The left side is greater than the right side which means that the given statement is always true. In this case there is no real number that makes the expression undefined. Determine the domain and range.

The domain of the expression is all real numbers except where the expression is undefined. Its vertex will 1.
