This question tests the student's ability to find the y-coordinate of the vertex of a quadratic function given in intercept/factored form.
Key Concept Explanation
The y-coordinate of the vertex of a quadratic function in intercept/factored form is found by substituting the x-coordinate of the vertex (which is the same as the axis of symmetry) back into the function.
