Given that
The graph is
And we have to find the zero of the f(x).
Explanation -
Since the line intersects the x and y-axis at -5 and 2 respectively. So the x and y coordinates will be -5 and 2.
The function is f(x) and it is labeled at the y-axis so the zero of the function is 2.
So C is the correct answer.
And the final answer is 2.
