Tell whether the graph opens upward or downward. Then find the axis of symmetry and vertex of the graph of the function.
y=-1/4x^2-24

y=-1/4x^2-24
Hints:
If the leading coefficient of a quadratic expression is negative, it opens downwards.
y=ax²+bx+c,
The axis of symmetry is at the line
y=-b/2a

Which one is the B in my equation?

y=ax²+bx+c,
b is the coefficient of the term in x.
Since your expression does not have an x-term, b=0.

Thank you!

You're welcome!
