What you should know for this case is that all quadratic functions represent a parabola.
We have then that the function with vertice (-2, 0) is:
y = (x-2) ^ 2
Notice that if you substitute the value x = -2 in the equation then y = 0
Answer:
y = (x-2) ^ 2

Answer: room 101 and room 107
Step-by-step explanation:
In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3
In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.
In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3
Therefore, room 101 and room 107 have the same ratio.
The base value is the current value
Good luck! I hope this helps!
