• None of the above

• Solve the equation by factoring

• Graph the equation again

What is the result of graphing the equation x^2 + 8x = -16?

• x = -8

• x = 4

• x = -4

• x = 8

What indicates that a quadratic equation has no real solutions when graphed?

• The graph does not touch the x-axis

• The graph touches the x-axis once

• The graph touches the x-axis twice

• The graph is a straight line

How can the line of symmetry help in graphing a quadratic equation?

• All of the above

• It indicates equal values on both sides of the graph

• It helps in finding the vertex of the parabola

• It shows where the maximum value occurs
