2 solutions

The graph never intersects the x-axis so f(x) has no zeroes.

Another way to solve the question if the graph is not given.

The discriminant is negative, so f(x) has no zeroes.

Solved it the same way ;)

No real zeroes, but it ask for zeroes

Indeed, due to it is a cuadratic function it must just have 2 roots as Gauss said (I remember; please, correct me). The problem is that thoses roots or zeros are not real, they are imaginary zeros
