Graphing Quadratics Review

To find the vertex in standard form, you must first find the axis of symmetry. The formula for that is x =

• -2b/a

• 2a/b

• -2a/b

• -b/2a

Which shows STANDARD FORM of a quadratic?

• 
• 
• 
• 

• x = -10

• x = -5

• x = 5

• x = 4

• (5,3)

• (5,-3)

• (5,47)

• (5,-33)

What is the y-intercept of this parabola?

• (-5,0)

• (-2,-9)

• (1,0)

• (0,-5)

Determine the vertex of the parabola:
y = 5x² - 20x + 13

• (5, -7)
• (-2, -7)
• (2, -7)
• (-7, -2)
