Use the graph to determine the solutions.

• -1 and -3

• 1 and -3

• 1 and 3

• -1 and 3

Convert to vertex form.

• y=3(x+1)² - 8

• y=3(x-1) ² - 8

• y=3(x+2)² - 8

• y=3(x-2)² - 8

Convert to vertex form.

• y=-(x-5)² + 21

• y=-(x+5)² + 21

• y=-(x+10)² + 21

• y=-(x-10)² + 21

• Axis of Symmetry: x = 10
  Vertex: (10, -28)

• Axis of Symmetry: x = 5
  Vertex: (5, -3)

• Axis of Symmetry: x = -5
  Vertex: (-5, -103)

• Axis of Symmetry: x = 5
  Vertex: (5, 47)

Give the domain and range for the graph shown.

• D: all real numbers
  R: y $\ge$   -4

• D: -2 $\le$   x $\le$   4
  R: y $\ge$   -4

• D: -2 $\le$   x $\le$   4
  R: y $\ge$   -4

Select the quadratic equation(s) that have two roots.

• y = x²-8x-20

• y = x² +3

• y = x²-2x+1

• y = x²-25

• y = 4x² +12x+9

Solve by factoring \(x^2-7x=44\)
