What Is The Domain Of Y X
If you don t know what the graph looks like just plot a bunch of points.
What is the domain of y x. So the domain is stated as oo 3 uu 3 oo. The domain is all values of that make the expression defined. Domain x as for all real values of x y is defined but it is given that x 0 so domain is 0.
The range is all possible values of y. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. But in this case since square root is in denominator it can t be equal to zero.
The range of an even indexed radical starts at its starting point and extends to infinity. Equating the denominator to zero and solving gives the value that x cannot be. If the denominator is equal to 0 the function is typically undefined.
Therefore at x 3 the function is undefined. Use the graph. In this case there is no real number that makes the expression undefined.
X 3 0 the function is undefined. The domain is all values of that make the expression defined. The lower bound of the range for secant is found by substituting the negative.
The given function is y x as domain is that values of x for which y exists and range is those values of y for which x exists. X as x is defined for only. This website uses cookies to ensure you get the best experience on our website.
