§6.2 Solving Quadratic Equations by Graphing When a quadratic function is set equal to a value, the result is a quadratic equation. The solution of a quadratic equation are called the roots of the equation. One method for finding the roots of a quadratic equation is to find the zeros of the
related quadratic function. The zeros of the function are the x-intercepts of its graph. These are the solutions of the related equation because f(x) = 0 at those points. The zeros of the function graphed at the right
are -1 and 2.

§6.2 Solving Quadratic Equations by Graphing Two Real Solutions Axis of symmetry: Note: The parabola opens up and the vertex is below the x-axis.
Therefore, the parabola must cross the x-axis at two distinct points. Solutions:

Slide5:

§6.2 Solving Quadratic Equations by Graphing One Real Solution Axis of symmetry: Note: The parabola opens up and the vertex is on the x-axis.
Therefore, the parabola only touches the x-axis at the vertex (1 point). Solution:

Slide6:

§6.2 Solving Quadratic Equations by Graphing No Real Solution Axis of symmetry: Note: The parabola opens down and the vertex is below the x-axis.
Therefore, the parabola never crosses the x-axis. Solution: No REAL solution.
