根据横坐标计算贝塞尔曲线纵坐标

The issue only provides a Java getBezierY method and does not name a repository file or test. First clarify the intended Bézier inputs, expected output, and requested change, then locate where this method belongs. Done should include a defined result for the stated x-coordinate cases and verification against agreed examples.
