Question

Using the graph as your guide, complete the following statement. The discrimination of the function is_____.

Answer 1

Recall the following:

• If the discriminant equals zero, the function has one real zero.

,

• If the discriminant is positive, the function has two real zeros.

,

• If the discriminant is negative, the function has two imaginary zeros.

Note that since the graph of the function intersects the x-axis at two points, the function has two real zeros.

Since there are two zeros, it follows that the discriminant must be positive.

The correct option is C.
