Since the axis is vertical, you know it's
y = a(x-h)^2 + k
Since the vertex is at (0,0), you know that h=k=0, and thus
y = ax^2
1/8 = 25a
a = 1/200
so,
y = 1/200 x^2
All the data you needed was there. Just gotta read it carefully.
Find the standard form of the equation of the parabola with the given characteristics and vertex at the origin. Passes through the point (-5, 1/8); vertical axis.
There is no focus of the parabola or equation given, so how am I suppose to solve this problem?
