Which types of dilation are the given scale factors?Select Expansion or Contraction to correctly describe the type of dilation for each given scale factor.Scale Factors: -5 (Expansion or Contraction?)-1/4 (Expansion or Contraction?)3.5 (Expansion or Contraction?)6/7 (Expansion or Contraction?)
Accepted Solution
A:
-5 is an expansion -1/4 is a contraction 3.5 is an expansion 6/7 is a contraction
If the scale factor is larger than 1, then it's an expansion. If it's less than 1, then it's a contraction.
