The vertical extent of the graph is 0 to 4 4 so the range is 4 0 4 0.

Find domain and range examples.

The domain is all values that x can take on. Without using a graph. The valid values for a given dependent variable y are collectively called the range. Find the domain and range of the radical function the acceptable values under the square root are zero and positive numbers.

Here are some examples illustrating how to ask for the domain and range. We observe that the graph corresponds to a continuous set of input values from 2 2 to 3. Find the domain and range. Find the domain and range of the function.

Add to both sides of the equation. Y 2 x 3. Determine the domain and range of the given function. Find the domain and range of the function f f.

Domain and range tips for entering queries.

The domain is all values of that make the expression defined. Find the domain and range of the function. The valid values for a given independent variable x are collectively called the domain. Set the denominator in equal to to find where the expression is undefined.

Thus the domain of the function is 2 3 2 3 also the variation in the function output is in the continuous interval from 1 1 to 4. To avoid ambiguous queries make sure to use parentheses where necessary. F x x 2 x 2 9 displaystyle f left x right frac sqrt x 2 x 2 9 f x x2 9x 2. For example in the function y f x 2 x y x is independent and y is dependent in other words y is a function of x.

The only problem i have with this function is that i cannot have a negative inside the square root. Mathbf color green mathit y sqrt 2 mathit x 3 y 2x 3. Square root of cos x. We can observe that the horizontal extent of the graph is 3 to 1 so the domain of f f is 3 1 3 1.
