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
Thank you for 2 but for 1 you have to make the equation.
x=2 IS the equation
