Domain Of Function Y Square Root Of X
I guess instead of making x squared 4 greater than or equal to zero and solving for x i could just simplify it to make it y x 2.
Domain of function y square root of x. Y square root 13 x since we can t take square roots of negative numbers we have to look at what values of x will make your square root a negative number. X 7 b. But 1 is not ok.
I know that to find the domain anything under the radical has to be greater than or equal to zero because it can t be a negative number but when you make x squared 4 greater than or equal to zero and solve for x you the square root of 4. What is the domain of the function y square root x 7. 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.
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. 13 14 1 so your domain is all real numbers less than or equal to. The range of an even indexed radical starts at its starting point and extends to infinity.
You can get to. Find the domain of the function. 5 points sperla1212 asked 01 22 2020.
Set the radicand in greater than or equal to to find where the expression is defined. I know that to find the domain anything under the radical has to be greater than or equal to zero because it can t be a negative number but when you make x squared 4 greater than or equal to zero and solve for x you the square root of 4. X 0 x 0.
