Question Analysis
This question assesses the student's ability to find the y-coordinate of the vertex for a quadratic function in intercept/factored form. The key is to first determine the x-coordinate of the vertex (axis of symmetry) and then substitute it back into the function to find the y-coordinate.

Key Concept Explanation
The vertex of a quadratic function in intercept form has an x-coordinate given by the axis of symmetry . To find the y-coordinate, substitute this x-value back into the function.

Step-by-step Solution
1. Identify the x-intercepts from the given function: and .
2. Calculate the x-coordinate of the vertex (axis of symmetry):
