### Polynomial Function and its Graph

The graph of a polynomial function is given.

\[P(x) = \frac{1}{9}x^4 - \frac{4}{3}x^3\]

![Graph of Polynomial Function](https://example.com/graph.png)

#### Graph Description
The provided graph displays a polynomial function, which is plotted on a Cartesian coordinate system with axes labeled \(x\) for the horizontal axis and \(y\) for the vertical axis. The graph shows a red curve representing the polynomial function.

#### Steps to Solve

**(a)** *From the graph, find the x- and y-intercepts. (If an answer does not exist, enter DNE.)*

- **x-intercepts**: Identify the points where the curve crosses the x-axis. There are typically one or more x-intercepts.
  
  \[
  (x, y) = ( \ \ \ \ , \ \ \ \ ) \quad \text{(smaller x-value)}
  \]
  
  \[
  (x, y) = ( \ \ \ \ , \ \ \ \ ) \quad \text{(larger x-value)}
  \]

- **y-intercept**: Identify the point where the curve crosses the y-axis. There should be one y-intercept.
  
  \[
  (x, y) = ( \ \ \ \ , \ \ \ \ )
  \]

**(b)** *Find the coordinates of all local extrema. (If an answer does not exist, enter DNE.)*

- **Local minimum**: Identify the lowest points on the curve within a particular interval where the curve changes direction from decreasing to increasing.
  
  \[
  (x, y) = ( \ \ \ \ , \ \ \ \ )
  \]

- **Local maximum**: Identify the highest points on the curve within a particular interval where the curve changes direction from increasing to decreasing.
  
  \[
  (x, y) = ( \ \ \ \ , \ \ \ \ )
  \]

Please refer to the given graph to determine the exact values of the intercepts and the local extrema.
