Domain of function y square root of x. The restriction here is that what is inside the square root must be greater than or equal to 0. The range of an even indexed radical starts at its starting point and extends to infinity. But 1 is not ok. The domain is all values of that make the expression defined.
What is the domain of the function y square root of x plus 4 14490392 1. We can also graph a function to find its do. We can take the square root of zero it equals zero. What is the domain of the function y square root x 7.
13 14 1 so your domain is all real numbers less than or equal to. Add to both sides of the inequality. X 7 b. What is the domain of the function y square root of x plus 4 see answers 1 ask for details.
How to recognize the domain and range of a function by considering the possible inputs and outputs of a function. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. 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. 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.
You can get to. 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. X 0 x 0. 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.
Find the domain and range y square root of x 3. 12 works 13 works but 14 doesn t work. Set the radicand in greater than or equal to to find where the expression is defined. Hence x 1 0 the solution set to the above inequality is the domain of f x and is given.
Find the domain of the function. 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. 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. All real numbers answer by rapaljer 4671 show source.
You can put this solution on your website. So please see my own non traditional explanation of functions domain and range.
