Answer:15
Step-by-step explanation:
2. y=x-3
3. y=3x+1
4. y=-3x-3
Answer: y < 1
<u>Step-by-step explanation:</u>

The first function has the range of y < -4
The second function has the range of y = -3
The third function has the range of y < 1
The largest y-value is 1 and the smallest y-value is -∞, therefore the range (y-values) are from -∞ to 1 → y < 1
