We have given


We can write h as function of x


The possible  zeros of h(x) is 2 ,because h(x) is polynomial of degree 2.So it has maximum two zeros (It is not necessary that all zeros are real ).Lets draw it graph ,then try to discuss


x=0 then h(x)=24

Thus maximu rise of water= 24 units.

fortunately I can  draw its graph.
