Answer:
[-20.25;+∞).
Step-by-step explanation:
1) according to the properties of the given parabola the minimum is:

2) y₀=-20.25 means, the value -20.25 is minimum of the range, the maximum →+∞;
3) finally, the range y≥-20.25.
 
        
             
        
        
        
Answer 
Find out the how many games did the teams lose .
To prove
Formula

As given
Salem High School's winter sports teams WON 72% of their games last season.
 If the teams played 50 games .
Percentage = 72%
Total value = 50
Put in the formula


Number of games win = 36 
Number of  games teams loses = Total number of games - number of games win
                                                           = 50 - 36
                                                            = 14 
Therefore the number of games  team loses are 14 .
