PLZ HELP! WILL MAKE A BRAINLIST Which types of dilation are the given scale factors?

attashe74 [19]

Answer:

see explanation

Step-by-step explanation:

For a given scale factor k

If k > 1 then expansion

If k < - 1 then expansion in the opposite direction

If 0 < k < 1 or - 1 < k < 0 then contraction

k = - 2 ← expansion in opposite direction

k = 1.5 ← expansion

k = $\frac{1}{4}$ ← contraction

k = - $\frac{6}{7}$ ← contraction
