Question

What is the equation of the axis of symmetry for the function x=1/8(y+3)^2-1

Answer 1

y = -3

Explanation:

x = ⅛ (y + 3)² − 1

This is a horizontal parabola, so the axis of symmetry is a horizontal line, y = k.

The vertex of the parabola is (-1, -3). The axis of symmetry passes through the vertex. Therefore, the equation is y = -3.
