Domain Of Y Square Root Of X 2
Algebra expressions equations and functions domain and range of a function.
Domain of y square root of x 2. Therefore the domain of this equation is the set of all real numbers. Find the domain for so that a list of values can be picked to find a list of points which will help graphing the radical. Examples on how to find the domain of square root functions with solutions example 1 find the domain of function f defined by f x x 1 solution to example 1. Since we are dealing with x 2 within the square root sign then any real number can be substituted for x and the result will be positive.
Hence x 1 0. X 2 0 x 2 0. For f x to have real values the radicand expression under the radical of the square root function must be positive or equal to 0. To give you some examples.
Graph y square root of x 2. What is the domain and range of y sqrt x 2 9. Find the domain and range y square root of x 2 y x 2 y x 2 set the radicand in x 2 x 2 greater than or equal to 0 0 to find where the expression is defined.
