-6 is not in the domain of f(x) but is in the range of f(x)
Step-by-step explanation:
we have
Find the domain of the function
we know that the radicand must be greater than or equal to zero
so
The domain is all real numbers greater than or equal to 7
The range is the interval -----> (-∞,1]
All real numbers less than or equal to 1
see the attached figure to better understand the problem
therefore
The statement that best describes the function f(x) is
-6 is not in the domain of f(x) but is in the range of f(x)
