Question

What are the apparent zeros of the function graphed above?

A : {4,2}
B : {0,2}
C : {-1,2}
B : {-2,1,2}

Answer 1

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.

Answer 2

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 .
