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
<u><em>Verify each case</em></u>
case 1) 2

----> is a enlargement
case 2) 1/2

----> is a contraction
case 3) -2

----> is a enlargement
case 4) -1/2

----> is a contraction
