Question

Which of the following options best describes the zeros of the quadratic function above?

Answer 1

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.

Answer 2

Answer:

B. 1 real zero

Step-by-step explanation:

On the graph, we can see that the function intersects the x-axis at one point.  This means there is 1 real zero.
