To solve $y = \sin x$ based on the given points $(325, 212.5)$, $(425, 150)$, and $(560, 200)$, let's analyze the situation. We need to determine the relationship between these points and the sine function.

1. Understand the Problem: We are given three points that likely lie on a curve approximating the sine function, $y = \sin(x)$. However, the sine function ranges between -1 and 1, so it appears that the given points involve a transformation of the sine function, potentially involving vertical scaling and shifting.

2. Transforming the Function: Let's assume the general form is: $y = A \sin(Bx + C) + D$ where:

   • $A$ is the amplitude (vertical stretch/compression),
   • $B$ affects the period (horizontal stretch/compression),
   • $C$ is the horizontal shift,
   • $D$ is the vertical shift.

3. Using the Points to Solve: We substitute each point into the transformed sine function to form a system of equations. Solving this system would allow us to determine $A$, $B$, $C$, and $D$.

However, this involves nonlinear equations and could be complex to solve manually. A better approach is to apply curve fitting techniques using these points to determine the parameters of the sine function that best fits these points.

Would you like a detailed step-by-step solution on how to solve this system, or should I graph the points and the sine function approximation?
