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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F800e794d-e6c7-4d68-9658-55331d2f099b%2Fd9ced079-a7b8-4ad2-a5c4-59b897210885%2Fx8ofdhs_processed.png&w=3840&q=75)

Transcribed Image Text: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.
