Solve Quadratic Equations by Graphing

• x = -2 and x = 1

• x = -1 and x = 2

• x = 2 only

• x = -1 only

When solving a quadratic equation graphically we look at the:

• Origin

• x-intercept

• y-intercept

Determine the solutions of the graph:

• No Solutions

• (-3, 0) and (-1, 0)

• Infinity Many Solutions

• (-1, 0)

Determine how many zeros:

What is another word that describes the zeroes of a quadratic function?  

• y-intercepts
• vertex
• x-intercepts
• maximum

What are the x- intercepts?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

What are the green dots called?

• vertex
• parabola
• roots or x-intercepts

What is the green dot on the parabola called?

• maximum
• minumum
• roots
• zeros

Does this graph have a maximum or minimum?

• Minimum
• Maximum

What is the green dashed line called?

• roots or x-intercepts
• parabola
• axis of symmetry
• line of dashes
