• Draw a straight line on the graph to find the solutions

• Use the quadratic formula to find the solutions

• Count the number of turning points on the graph to find the solutions

If a quadratic equation has two x-intercepts, what does it tell you about the solutions?

• Two real solutions

• No real solutions

• One real solution

• Two complex solutions

What is the significance of the vertex of a quadratic equation on its graph?

• It represents the maximum or minimum point on the graph.

• It indicates the slope of the graph

• It represents the x-intercept of the graph

• It has no significance on the graph

How can you determine the nature of the solutions of a quadratic equation from its graph?

• By analyzing the y-intercepts of the graph

• By analyzing the x-intercepts of the graph

• By analyzing the slope of the graph
