• $78 per game

• $41 per game

• $124 per game

Which function is equivalent to g(x) =  $2x^2$  + 7x + 6

• (x + 6) (x + 1)

• (2x + 1) (x +3)

• (x + 2) (2x + 3)

• (x + 4) (x + 3)

The graph of a quadratic function is shown on the grid.  Which function is best represented by this graph?

•  $f\left(x\right)\ =\ x^2-6x$  
  

•  $f\left(x\right)=x^2+x\ -6$  
  

•  $f\left(x\right)=2x^2+4x\ +3$  

•  $f\left(x\right)\ =\ x^2+x+6$  

Which system of equations does the graph represent?

• y = 1/3x + 3

  y = -5/3x - 3

• y = 5/3x + 3

  y = -1/3 - 3

• y = -4/3x + 3

  y = 1/3x - 3

• y = -5/3x + 3

  y = 1/3x - 3
