x = 2 is the zero of the graph
Here, we are to calculate the zero of the graph
When we talk of the zero of the graph, we are talking of the root of the equation
It simply is the value of x when the graph crosses the x-axis
From what we can see, we can see that the graph crossses the x-axis at the point x = 2
Thus, x = 2 is the zero of the graph
