Quadratics Review Graphs

Use the graph to determine the solutions.

• -1 and -3

• 1 and -3

• 1 and 3

• -1 and 3

Answer explanation

The solutions are where the graph intersects the x-axis, which are at x=1 and x=3.

Which value is the vertex?

• (-4, 0)

• (-1, -9)

• (0, -8)

• (2, 0)

Answer explanation

The vertex is (-1, -9) as it represents the maximum or minimum point of the parabola. In this case, it is a minimum point as the parabola opens upwards.

The line that makes the graph symmetric is the:

• Solution Set

• Quadratic Function

• Intercept Formula

• Axis of Symmetry

Answer explanation

The correct choice is the Axis of Symmetry, as it is the line that divides a graph into two symmetric parts.

Choose the correct graph that matches the equations.
