Answer:

x = - 1

Step-by-step explanation:

Given a parabola in standard form , f(x) = ax² + bx +c ( a ≠ 0 )

Then the axis of symmetry is calculated using

x = - \frac{b}{2a}

f(x) = x² + 2x - 8 ← is in standard form

with a = 1 and b = 2 , then axis of symmetry is

x = - \frac{2}{2} = - 1, that is

x = - 1
