At vertex, x=6/10=0.6
Try
f(-1)=-2
f(0)=9
f(2)=-1
So -1 and +2 could be approximate zeroes of f(x).
select the approximate value of x that are solutions to f(x)=0 where f(x)= -5x^2+6x+9

The local zoo has two water tanks for the elephant exhibit that are leaking One water tank contains 12 gal of water and is leaking at a constant rate of 3 gal/h. The second water tank contains 8 gal of water and is leaking at a constant rate of 5 gal/h. When will the two tanks have the same amount of water? Explain. Let x = the number of hours the tanks are filling and let y = the number of gallons in the tank.
