Question Analysis
This question tests the student's ability to calculate the y-coordinate of the vertex for a quadratic function given in intercept/factored form. The function is , and the y-coordinate of the vertex is found by substituting the x-coordinate of the vertex back into the function.

Key Concept Explanation
The y-coordinate of the vertex for a quadratic function in intercept/factored form is found by first determining the x-coordinate of the vertex (which is the same as the axis of symmetry, ) and then substituting this 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):
