As you probably can notice, the graph corresponds to a quadratic equation and, since the parabola opens downwards, the equation has to include a term of the form -ax^2 (a>0).
The zeros of a graph are the points that satisfy the equation f(x)=0
From the graph, we can see that there are no points of the form (x,0) for any value of x. Therefore, the graph has no zeros
