Writing Quadratic Equations

Which equation has a vertex of (-3, 4)?

• y = 2(x+3)² + 4
• y = (x+3)² - 4
• y = (x-3)² + 4
• y = 2(x - 3)² + 4

What is the vertex of the parabola: y=2(x-3)²+4

• (3,4)
• (-3,4)
• (3, -4)
• (-3,-4)

What is the vertex of y = 2(x - 3)² + 6

• (-3, -6)
• (3, -6)
• (-3, 6)
• (3, 6)

Write y = x² + 4x - 1 in vertex form.

• y = (x - 2)² + 5
• y = (x + 2)² - 5
• y = (x + 2)² - 1
• y = (x +2)² + 3

Write y = x² - 18x + 52 in vertex form.

• y = (x - 9)² + 113
• y = (x + 9)² - 29
• y = (x - 9)² + 52
• y = (x - 9)² - 29

Convert the equation y= 5x² - 40x + 67 into vertex form.

• y= -5(x + 4)² + 13

• y= 5(x + 4)² - 13

• y=5(x - 4)² - 13

• y= 5(x - 13)² + 4
