Answer:
The interval notation for the domain is .
Step-by-step explanation:
Consider the provided information.
It is given that
We need to find the value of .
Put the value of g(x) in .
....(1)
Now, put x=x-7 in
From equation 1.
The domain of the function is the set of input values for which a function is defined.
Here, the value of should be greater or equal to 0 as the square root of a negative number is not real.
Domain=
The value of x is all real number greater than .
Hence, the interval notation for the domain is .
