Quadratic equation (in our case ) has the following solutons:



For these solutions to exist, the discriminant should not be a negative number.

First, we need to compute the discriminant : .

Discriminant d=36 is greater than zero. That means that there are two solutions: .




Quadratic expression can be factored:

Again, the answer is: 6, 0. Here's your graph:

b. The function has a minimum value because it opens upward and has a lowest point.
c. The vertex (lowest point) is (3,-9).
c. The axis of symmetry is x = 3.
