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^224

y=1/4x^224
Hints:
If the leading coefficient of a quadratic expression is negative, it opens downwards.
For a general quadratic equation
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 xterm, b=0. 
Thank you!

You're welcome!
