Which of the following is the graph of the quadratic function? y=x^2+4-12   

 

You mistyped the question.  It should be 4x not just 4. 

 

x2 + 4x – 12  factors to (x + 6)(x – 2)  

 

Therefore y equals 0 when x equals –6 and when x equals +2 

 

Find which curve crosses the x-axis (i.e., y=0) at –6 and +2   

 

The print is too small for me to see well, but I think it's showing that on Graph A
