What are the domain and range of the function f(x)=square root of x-7+9

Domain:

Range:

Step-by-step explanation:

We have been given a function . We are asked to find the domain and range of our given function.

We know that a square root function is not defined for negative numbers, so domain of our given function would be .

Therefore, the domain of our given function is all values of x greater than or equal to 7 that is .

We know that range of a radical function of form is .

Upon looking at our given function, we can see that value of k is 9, therefore, the range of our given function is all values of y greater than or equal to 9 that is .
