Question

Find the axis of symmetry for this parabola:

Answer 1

Answer:

x = - 1

Step-by-step explanation:

The equation of the axis of symmetry for a parabola in standard form

y = ax² + bx + c : a ≠ 0 is found using

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

y = - x² - 2x - 5 ← is in standard form

with a = - 1 and b = - 2, thus equation of axis of symmetry is

x = - $\frac{-2}{-2}$ = - 1

Equation of axis of symmetry is x = - 1
