Domain Y Square Root X
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.
Domain y square root x. Add to both sides of the inequality. X 0 x 0. The domain is all values of that make the expression defined. Find the domain and range y square root of x y x y x set the radicand in x x greater than or equal to 0 0 to find where the expression is defined.

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. Graph y square root of x y x y x find the domain for y x y x so that a list of x x 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. Set the radicand in greater than or equal to to find where the expression is defined. 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. Then y sqrt 4 0 2 2 so the function is defined on 2 2.
