**Linear Approximation in Calculus**

**Problem 4:**

Consider a function \( y = y(x) \) that is differentiable and defined near \( x = 2 \). The function satisfies the conditions \( y(2) = -1 \) and \( x^2 + 3xy^2 + y^3 = 9 \).

**Objective:**

Use the linear approximation to estimate the value of \( y(1.91) \). This involves finding the change in \( y \) using the given function and conditions.
