what does solution mean? does it mean f(x)=0 at some x?

I think there are types of function where it is negative at x=0 and positive at x=1

your problem is "A continuous function..." right? where does step function come from?

step function is not a continuous function,friend

think of a parabola with a minimum below the x-axis? Also consider MVT.
