Answer:

x = - 1

Explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 ) , then the equation of the axis of symmetry is

x = -
(b)/(2a)

y = - 2x² - 4x - 11 ← is in standard form

with a = - 2 and b = - 4 , thus

x = -
(-4)/(-4) = - 1

x = - 1 is the equation of the axis of symmetry
