Domain- [-6, infinite) 
Range: [0, Infinite) 
This is because you get the x from the square root (-6) and the y from the invisible 0. Because it doesn’t have a negative x, it goes up.
        
             
        
        
        
Answer:
$0.75 per song
Step-by-step explanation:
Given that the relationship between variable s and c is a proportional relationship, and is represented by the equation, c = 0.75s.
Where, 
c = total costs
s = number of songs
The constant of proportionality, k, = 0.75.
Thus, 0.75 represents the cost per sing downloaded.
The answer is: 
✔️$0.75 per song

Answer:
B
Step-by-step explanation:
Consider all options:
A. Transformation with the rule 

is a reflection across the x-axis.
Reflection across the x-axis preserves the congruence.
B. Transformation with the rule 

is a dilation with a scale factor of  over the origin.
 over the origin.
Dilation does not preserve the congruence as you get smaller figure.
C. Transformation with the rule 

is a translation 6 units to the right and 4 units down.
Translation 6 units to the right and 4 units down preserves the congruence.
D. Transformation with the rule 

is a clockwise rotation by  angle over the origin.
 angle over the origin.
Clockwise rotation by  angle over the origin preserves the congruence.
 angle over the origin preserves the congruence.
