Answer:
1/2
-1/2
Step-by-step explanation:
we know that
If a dilation produce a contraction that means that the absolute value of the scaling factor is less than 1
If a dilation produce an enlargement that means that the absolute value of the scaling factor is greater than 1
Verify each case
case 1) 2
[tex]\left|2\right|=2[/tex]
[tex]2 > 1[/tex] ----> is a enlargement
case 2) 1/2
[tex]\left|1/2\right|=1/2[/tex]
[tex]1/2 < 1[/tex] ----> is a contraction
case 3) -2
[tex]\left|-2\right|=2[/tex]
[tex]2 > 1[/tex] ----> is a enlargement
case 4) -1/2
[tex]\left|-1/2\right|=1/2[/tex]
[tex]1/2 < 1[/tex] ----> is a contraction
