Answer
y=-1/16x^{2}* (x+3)^{2}(x-3)
Work Step by Step
From the graph, x=-3 so 0 and 3 are the roots.
The curve does not cross the x axis at -3, so there are the multiple roots.
So, y=Kx^{2}(x+3)^{2}(x-3)
And y(1)=2
y(1)=k(1)^{2}*(1+3)^{2}*(1-3)
2=K(-32)
K = -1/16
The possible formula is:
y=-1/16x^{2}* (x+3)^{2}(x-3)
