value Equation in

vertex form 𝒚 = −(𝒙 + 𝟓)^𝟐 − 3
find the Equation of the axis
of symmetry

1 answer

The equation of the axis of symmetry for a quadratic function in vertex form is 𝒙 = 𝒉, where 𝒉 is the x-coordinate of the vertex.

In this case, the vertex form is 𝒚 = −(𝒙 + 𝟓)^𝟐 − 3, which means the vertex is at (-5,-3).

Therefore, the equation of the axis of symmetry is 𝒙 = -5.
