Answer:
Add x x and 0 0 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=x+7 f - 1 ( x ) = x + 7 is the inverse of f(x)=x−7 f ( x ) = x - 7
Step-by-step explanation:
Answer:
The range is 
The graph in the attached figure
Step-by-step explanation:
we have

The domain is the interval
----> given problem
Remember that
The domain of a function is the set of all possible values of x
The range of a function is the complete set of all possible resulting values of y, after we have substituted the domain.
To find out the range of the function , find the value of y for each value of x
so
For x=-2 ----> y=-2-7=-9
For x=-1 ----> y=-1-7=-8
For x=0 ----> y=0-7=-7
For x=1 ----> y=1-7=-6
For x=2 ----> y=2-7=-5
therefore
The range is
