Answer:
range ={-6,-2,4,8}
Step-by-step explanation:
The given function is
[tex]f(x) = 2x + 2[/tex]
The domain is given as:
domain = {-4,-2, 1,3}
To find the range, we plug in the domain and solve for the corresponding range value.
When x=-4,
[tex]f( - 4) =2 \times - 4 + 2 = - 8 + 2 = - 6[/tex]
When x=-2,
[tex]f( - 2) =2 \times - 2+ 2 = - 4+ 2 = - 2[/tex]
When x=1,
[tex]f( 1) =2 \times 1 + 2 = 2 + 2 = 4[/tex]
When x=3,
[tex]f( 3) =2 \times 3 + 2 = 6 + 2 = 8[/tex]
Therefore the range is {-6,-2,4,8}
