Convert the equation        y= x² - 2x - 5 into vertex form. 

• y= (x-1)²-6
• y= -(x-1)²-6
• y= (x+1)²-6
• y= -(x+6)²-1

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

Convert to vertex form.

• y=2(x+3)² - 9
• y=2(x-3)² - 9
• y=2(x+6)² - 9
• y=2(x-6)² - 9

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

If given the equation         y= 3(x + 5)² - 4, what is the vertex of the parabola?

• (5, -4)
• (-5, -4)
• (-15, -4)
• (15, -4)

The standard form of a quadratic function is...

• ax² + bx + c
• a(x - h)² + k
• y - y₁ = m(x - x₁)
• Ax + By = C

Convert
 f(x) = 3(x - 5)² - 1 
to standard form.

• f(x) = 3x² -30x + 74
• f(x) = 3x² -10x + 24
• f(x) = 3x² -30x + 24
• f(x) = 3x² -30x + 75

Convert
 f(x) = 2(x - 2)² +9
to standard form.

• f(x) = 2x² + 8x + 9
• f(x) = 2x² - 8x - 4
• f(x) = 2x² - 8x + 17
• f(x) = 2x² - 8x + 8

Convert
 f(x) = -4(x - 1)² +7
to standard form.

• f(x) = -4x² + 3
• f(x) = -4x² - 8x + 17
• f(x) = -4x² +8x - 11
• f(x) = -4x² +8x + 3

Multiply and turn to standard form

(2x + 9)(x - 1)

• 2x² -7x + 9

• 2x² +7x - 9

• 2x² +11x - 9

• 2x² -7x - 9
