So I have graphed it here:  https://www.desmos.com/calculator/tz96dkf4x9 

So since f(x)=0 at x=0 and x=4 (found using graph or quadratic formula where c=0)

We can guess that the function is positive after x=0

Using our graph we confirm that for every x greater than 0, f(x) is positive.  


Let me know if you have any further questions!
