To find the value of \( y \) based on your description, we would need the specific piecewise function and any relevant information or criteria that would allow us to calculate \( y \). If you provide the details of the piecewise function, I can help calculate the value of \( y \).
Please provide additional information or context regarding how \( y \) is defined, or if there are specific conditions that apply to different parts of the piecewise function.
