Write the equation of the quadratic graph...

• y = (x - 2)² + 1

• y = - (x - 2)² + 1

• y = (x + 2)² - 1

• y = (x + 2)² + 1

• y = - (x + 2)² + 1

Name the following by degree...

3x² + 4x - 6

• Trinomial

• Linear

• Cubic

• Quadratic

• Quintic

Identify the vertex...

Write it in (x, y) form

Find the vertex...

y = (x + 4)² - 3

• (4, -3)

• (-4, -3)

• (4, 3)

• (-4, 3)

• (-3, 4)

Factor...

2x² + x - 15

• (2x - 5)(x + 3)

• (2x + 5)(x - 3)

• (2x + 3)(x - 5)

• (2x - 3)(x + 5)

• (2x + 15)(x - 1)

Solve for x by factoring...

x² + 5x - 14 = 0

• x = 7, 2

• x = -7, 2

• x = 7, -2

• x = -7, -2

• x = 14, -1
