# A bridge, riverbed can be modeled by h=0.005x2 + 24 how many zeros do you expect ? how high could the water rise before it can still use?

We have given

`h=.005x^2+24`

We can write h as function of x

`h(x)=.005x^2+24`

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

(h(x)-24)/(.005)=x^2

x=0 then h(x)=24

Thus maximu rise of water= 24 units.

fortunately I can draw its graph.
