Respuesta :

The zeros are the x coordinates of the points of the intersection of the graph of the function with the x-axis. 
We identify the following point (-1,0) and (2,O)

The correct answer is C then . 
The zeros of a function are the point where the graph of the function crosses/touches the x-axis.
It is the solution of the function when y = 0.

From the graph above, the graph crossed/touched the x-axis at the point (-1, 0) and (2, 0).

Therefore, the apparent zero's of the function is the set {-1, 2}.

Option C.
