Answer:
the parabola opens down
Step-by-step explanation:
Select the direction that this parabola opens.
y=-x^2/20
\(y=\frac{-x^2}{20}\)
To find the direction of the parabola y=ax^2 +bx+c ,we need to consider the value of 'a'
If 'a' is positive then the parabola opens up
If 'a' is negative then the parabola opens down
from the given equation
\(y=\frac{-x^2}{20}\)
The value of a=-1 which is negative
so the parabola opens down
