What is the axis of symmetry for the parabola defined by the equation y^2 = -12x?

What is the axis of symmetry for the parabola defined by the equation y^2 = -12x?

Step 1: Identify the form of the equation. The given equation is y^2 = -12x.
Step 2: Recognize that this equation is in the form y^2 = 4px, where p is a constant.
Step 3: Compare the equation y^2 = -12x with y^2 = 4px. Here, -12 can be written as 4p.
Step 4: Solve for p by setting 4p = -12. This gives p = -3.
Step 5: Understand that for parabolas in the form y^2 = 4px, the axis of symmetry is the line x = 0 (the y-axis).
Step 6: Conclude that the axis of symmetry for the given parabola is x = 0.
