Question Analysis
This question assesses the student's ability to find the axis of symmetry for a quadratic function in intercept/factored form. The axis of symmetry is the vertical line that passes through the midpoint of the x-intercepts.

Key Concept Explanation
The axis of symmetry for a quadratic function in the form is given by the formula . This line divides the parabola into two symmetrical halves and passes through the vertex.

Step-by-step Solution
1. Identify the x-intercepts from the given function: .
2. From the form
