Answer: The correct option is (B) 1 real zero.
Step-by-step explanation: We are given to select the option that best describes the zeros of the quadratic function in the graph.
The zeroes of a quadratic function are the x-intercepts of the function or the points where the graph touches X-axis.
That is, they are the points at which the value of y (or f(x)) becomes zero.
We can see from the graph that it touches the X-axis at the point (-1, 0) only.
So, the value of y is zero at only one point with the co-ordinates (-1, 0).
So, there is only one real zero of the graphed function.
Thus, the correct option is (B) 1 real zero.
