Question 10 of 10

Find the axis of symmetry of a parabola from vertex form.

‹

\( \text{What is the axis of symmetry of the parabola } y = -(x + 4)^2 + 1? \)

Choose one option:

Identify h from the bracket and set x = h.

Axis of symmetry passes through the vertex: \(x = h\) in \(y = a(x-h)^2 + k\).
