Answer:

The range is \{-9,-8,-7,-6,-5\}

The graph in the attached figure

Step-by-step explanation:

we have

y=x-7

The domain is the interval \{-2,-1,0,1,2\} ----> 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 \{-9,-8,-7,-6,-5\}

The graph in the attached figure
