Transcribed Image Text:**Using Transformations to Graph Rational Functions**
To graph the rational function \( r(x) = \frac{4x - 17}{x - 4} \) by transforming the graph of \( y = \frac{1}{x} \), follow these steps:
### Graph Description
**Top Left Graph:**
- The graph of the function is shown in purple and blue.
- It mirrors the shape of a typical hyperbola, which is the plot of \( y = \frac{1}{x} \).
- There is a vertical asymptote at \( x = 4 \) and a horizontal asymptote at \( y = 4 \).
**Top Right Graph:**
- Again, the hyperbolic shape is evident.
- Similar features are present with the vertical asymptote at \( x = 4 \) and a horizontal asymptote at \( y = 4 \).
**Bottom Left Graph:**
- This graph displays the consistent hyperbolic form.
- The vertical line \( x = 4 \) indicates the vertical asymptote.
- The horizontal asymptote remains at \( y = 4 \).
**Bottom Right Graph:**
- Demonstrates the same structural pattern as the previous graphs.
- The vertical asymptote occurs at \( x = 4 \), while the horizontal asymptote is at \( y = 4 \).
### Graph Analysis
- **Vertical Asymptote:** Occurs at \( x = 4 \) due to the denominator approaching zero.
- **Horizontal Asymptote:** Found at \( y = 4 \), determined by the leading coefficients of the polynomial.
These transformations of the base graph \( y = \frac{1}{x} \) depict how changes in the function \( r(x) = \frac{4x - 17}{x - 4} \) affect its graphical representation.

Transcribed Image Text:The image shows a webpage with four graphs depicting functions on Cartesian coordinates. Each graph includes a vertical asymptote (dashed blue line) and a horizontal asymptote (dashed blue line), with a red curve indicating the function's behavior near these asymptotes.
- **Top Left Graph**: The function approaches a vertical asymptote at \(x = 0\) and a horizontal asymptote at \(y = 0\). The red curve is located in the third and first quadrants.
- **Top Right Graph**: This function also has a vertical asymptote at \(x = 0\) and a horizontal asymptote at \(y = 0\). The red curve is located in the fourth and second quadrants.
- **Bottom Left Graph**: Similar to the others, this graph has vertical and horizontal asymptotes at \(x = 0\) and \(y = 0\), respectively. The red curve is prominently in the first and third quadrants.
- **Bottom Right Graph**: The function has the vertical asymptote at \(x = 0\) and the horizontal asymptote at \(y = 0\). The red curve appears in the second and fourth quadrants.
Below the graphs, there are input fields for entering the domain and range of the functions using interval notation. A checkbox beside these fields indicates that answers can be submitted for evaluation. There is also a "Need Help?" section with a "Read It" button for additional assistance.
Please use interval notation to enter your answers for the domain and range of these functions.
