Question

Using the graph as your guide, complete the following statement.

Answer 1

Because the parabola intercepts the x-axis only once, we conclude that the discriminant is 0.

What can we say about the discriminant?

For a quadratic equation:

y = a*x^2 + b*x + c

The discriminant is:

D = b^2 - 4ac

• If D = 0, there is only one real zero.
• If D > 0, there are two real zeros.
• If D < 0, there are two complex zeros.

In the graph we can see that the parabola intercepts the x-axis in its vertex, then the parabola has only one real zero, then we conclude that the discriminant is equal to zero.
