Question

What is the equation for the axis of symmetry for this quadratic function

Answer 1

Answer: x = -2

Step-by-step explanation: That axis of symmetry is the

fold line or the line that splits the parabola down the middle.

The line that makes this parabola symmetrical is x = -2.

So our axis of symmetry is x = -2.

An easy way to find it is average the zeros (x-intercepts) and multiply by 1/2.

So here, -4 + 0 is -4 and -4(1/2) is -2.

Answer 2

Answer:

The answer to your question is  x = -2

Step-by-step explanation:

Process

Identify the kind of curve. This is a vertical parabola that opens upwards.

The axis of symmetry is the line that divides the parabola into two identical sections.

This line must be a vertical line that passes through the Vertex.

The Vertex is the lowest point of the parabola.  Vertex = (-2, -4).

Then, the axis of symmetry must be x = -2
