1.Find the equation of the axis of symmetry of the parabola.

Enter the answer as an equation.

 

2. Find the vertex of the graph of $y = x^2 + 8x + 23.$

1 )    x= 2   (just by inspection)

 

2 )   Multiple ways to do this one

           re-arrange into vertex form:

                  (x+4)2 -16 + 23

                   (x+4)2 + 7                      vertex is   -4,7
