9.1 Solving Quadratic Equations Using Graphs and Tables

• The solution is the​ x-value where the graph crosses the​ y-axis.

• The solutions are the​ x- and​ y-values where the graph crosses the​ y-axis.

• The solution is the​ y-value where the graph crosses the​ y-axis.

• There are no real solutions.

Describe and correct the​ error a student made in stating the number of solutions of a quadratic equation. Explain.

• A quadratic equation cannot have two solutions.

• A quadratic equation can have any number of solutions.

• A quadratic equation must have at least one solution.

• The student left out that a quadratic equation could have one solution.
