  1. The function v is defined by v ( x ) = 12 ( x + 5 ) 2 7 .

Without graphing, determine if the vertex of the graph representing v shows the minimum or maximum value of the function.

  1. The vertex shows the maximum value.
  2. The vertex shows the minimum value.
  1. Choose the equation that matches the graph of parabola D .

  1. y = 1 3 ( x 6 ) 2 5
  2. y = 6 ( x 6 ) 2 5
  3. y = ( x 6 ) 2 5
  4. y = 2 ( x 6 ) 2 5
  1. Choose the equation that matches the graph B.

  1. y = 1 3 ( x 6 ) 2 5
  2. y = 6 ( x 6 ) 2 5
  3. y = ( x 6 ) 2 5
  4. y = 2 ( x 6 ) 2 5
