Question
**Problem Statement:**

Use implicit differentiation to find an equation of the tangent line to the curve at the given point.

**Equation:**
\[ x^{2/3} + y^{2/3} = 4 \]

**Point:**
\[ \left(-3\sqrt{3}, 1\right) \]

**Curve Type:**
Astroid

**Explanation:**

This problem involves finding the equation of the tangent line to a specific curve known as an astroid at the given point using implicit differentiation. An astroid is a type of hypocycloid with a distinctive star-like shape. The curve is defined by the equation \( x^{2/3} + y^{2/3} = 4 \). You are tasked with using implicit differentiation techniques to determine the slope of the tangent line at the specified point, \((-3\sqrt{3}, 1)\), and then formulating the equation of the tangent line.

The image shows a graph of a rational function. The graph is a symmetrical curve that resembles an hourglass shape. The function is plotted on a Cartesian coordinate plane with the x-axis and y-axis intersecting at the origin (0,0).

### Key Features of the Graph:
- **Axes Orientation**: The x-axis is labeled with numbers 0 and 8, with arrows indicating the positive direction of both the x-axis and y-axis.
- **Curve Shape**: The graph consists of two curved sections:
  - The upper part of the curve is symmetrical across the y-axis and peaks at the origin.
  - The lower part mirrors the upper part downward, forming an open loop.
- **Intercepts**: The curve crosses the x-axis at two points, including the origin (0,0).

This graph is useful for analyzing the properties and behavior of rational functions, especially those involving symmetry and intercepts.
