6.3 Introduction

Determine the vertex for each absolute value function

• (-3, -1)
• (-3, 1)
• (3, -1)
• (3, 1)

Determine the vertex of the function

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

Determine the vertex of the function.

• (0, -5)
• (0, 5)
• (-2, 5)
• (-2, -5)

Simplify:
(x-7)²

• x²-49
• x²+49
• x²-14x+49
• x²-14x-49

Multiply:

(y + 9)²

• y² +18y + 81

• y² + 81

• y + 9

• y² +18y + 18

• 3

• -3

Solve by taking square roots:

-3b² - 4 = 26

• k = ±2i√30

• k = ±i√30

• k = ±2i√10

• k = ±i√10

Factor the Trinomial:
x² - 8x + 15

• (x + 5) ( x + 3)
• (x - 5) (x - 3)
• (x + 15) (x - 1)
• (x - 7) (x - 8)

Factor:
x² + 6x + 20

• (x + 4)(x + 5)
• (x + 20)(x + 1)
• (x + 10)(x + 2)
• PRIME
