Answer:
Yes; domain: all real numbers; range: y 
0
Step-by-step explanation:
1. Use the vertical line test to see if it is a function.
2. Figure out what the lowest and highest point x can be. In this case x can be any number
3. Figure out what the lowest and highest point of y can be. In this case y is not negative, the lowest it can be is 0. So y 0
*Note: Domain are the x values & Range are the y values

Answer:
Yes, both shampoo and water will be enough
Given that:
Number of long and short hair member who can wash their hair ; with amount of water less than 5600 litres
To check if bathroom has enough water and shampoo for 8 long haired and 7 short haired members.
L = long-haired ; S = short-haired
70L+ 60S < 5600
Check the constraint for amount of water :
70L+ 60S < 5600
L = 8 ; S = 7
70(8) + 60(7) < 5600
560 + 420 < 5600
980 < 5600
Constraint satisfied
Number of long and short hair member who can wash their hair with shampoo not more than 2.5 litres
0.02L + 0.01S ≤ 2.5
L = 8 ; S = 7
0.02(8) + 0.01(7) ≤ 2.5
0.16 + 0.07 ≤ 2.5
0.23 ≤ 2.5 (constraint satisfied).
