I need the range and graph h please

Answer:
The range is {4,2,0,-2)
Step-by-step explanation:
The given function is [tex]h(x)=2-2x[/tex]
The domain is {-1,0,1,2}
To find the range we substitute the elements in the domain and calculate the corresponding images.
when x=-1
[tex]h(-1)=2-2(-1)=2+2=4[/tex]
When x=0,
[tex]h(0)=2-2(0)=2-0=2[/tex]
When x=1,
[tex]h(1)=2-2(1)=2-2=0[/tex]
When x=2,
[tex]h(2)=2-2(2)=2-4=-2[/tex]
Therefore the range is {4,2,0,-2)
