SOLUTION: Indicate the axis of symmetry of the parabola y = x^2 + 8x + 20

Question 250561: Indicate the axis of symmetry of the parabola
y = x^2 + 8x + 20

If your equation is in vertex form, then the axis of is
x= h in the general vertex form equation y = (x-h)2 + k
If your equation is in standard form, then the formula for the axis of symmetry is:
x = -b/2a from the general standard form equation y = ax2+bx + c
