Which scale factors produce a contraction under a dilation of the original image?

2

1/2

-2

-1/2

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

----> is a enlargement

case 2) 1/2

----> is a contraction

case 3) -2

----> is a enlargement

case 4) -1/2

----> is a contraction

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19
