Hyperbola Shift Left 86820F
1. **Problem Statement:**
Sketch the graph of the function \(y = \frac{6}{x+1}\) using transformations. Identify the domain, range, intercepts, and asymptotes.
2. **Formula and Important Rules:**
The base function is \(y = \frac{1}{x}\), a hyperbola with vertical asymptote at \(x=0\) and horizontal asymptote at \(y=0\).
Transformations:
- Horizontal shift by \(-1\) (because of \(x+1\) in denominator).
- Vertical stretch by factor 6.
3. **Domain:**
The function is undefined where the denominator is zero:
$$x+1=0 \implies x=-1$$
So, domain is \(\{x \mid x \neq -1, x \in \mathbb{R}\}\).
4. **Range:**
Since the function is a vertical stretch of \(\frac{1}{x+1}\), the horizontal asymptote remains at \(y=0\), which the function never reaches.
Thus, range is \(\{y \mid y \neq 0, y \in \mathbb{R}\}\).
5. **Intercepts:**
- \(x\)-intercept: Set \(y=0\), solve \(\frac{6}{x+1}=0\). No solution since numerator 6 \(\neq 0\), so no \(x\)-intercept.
- \(y\)-intercept: Set \(x=0\), then \(y=\frac{6}{0+1}=6\).
6. **Asymptotes:**
- Vertical asymptote at \(x=-1\) (denominator zero).
- Horizontal asymptote at \(y=0\) (limit as \(x \to \pm \infty\)).
7. **Summary:**
- Domain: \(x \neq -1\)
- Range: \(y \neq 0\)
- \(x\)-intercept: none
- \(y\)-intercept: 6
- Asymptotes: \(x=-1\), \(y=0\)
This matches the given information and describes the graph as a hyperbola shifted left by 1 unit and vertically stretched by 6.
