vertex is at the origin so it must be \[y=ax^2\] now we need \(a\) and since it looks like \[(4,4)\] i on the graph we know \[4=a\times 4^2=a\times 16\] so we get \[a=\frac{4}{16}=\frac{1}{4}\] and your equation is \[y=\frac{1}{4}x^2\]

It has to be one of these: y=x^2/4, y=x^2/4, y=x^2/2, or y=2x^2
