Increasing: (- inf , 0)
Decreasing: (0 , + inf)
Positive: (- 1 , 1 )
Negative: (- inf , -1) , (1 , + inf)
Maximum: (0,3) or just 3.

Answer:
C, D and E
Step-by-step explanation:
Given
Represent solid beads with S and clear beads with C
So:
Required
Select operations that give an equivalent ratio
First, we need to get the unit ratio
Divide through by 4
-- This means that, after any operation. The equivalent ratio must be 2: 5
Option A: Add 2 to S and 2 to C
Perform the operation
Divide through by 2
Option B: Subtract 8 from S and 6 from C
Perform the operation
Option C: Multiply S and C by 2
Perform the operation
Divide through by 8
Option D: Divide S and C by 4
Perform the operation
Option E: Multiply S and C by 18
Perform the operation
Divide through by 72
<em>From the calculations above, options C, D and E gave an equivalent of 2:5.</em>
