Question

I need the range and graph h please

Answer 1

The range is {4,2,0,-2)

Explanation:

The given function is
`h(x)=2-2x`

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

`h(-1)=2-2(-1)=2+2=4`

When x=0,

`h(0)=2-2(0)=2-0=2`

When x=1,

`h(1)=2-2(1)=2-2=0`

When x=2,

`h(2)=2-2(2)=2-4=-2`

Therefore the range is {4,2,0,-2)
