1. **State the problem:** Find the horizontal asymptote, vertical asymptote, x-intercept, y-intercept, and hole of the function $$f(x) = \frac{3x - 7}{4x + 14}$$.
2. **Horizontal asymptote:** For rational functions $$\frac{P(x)}{Q(x)}$$ where degrees of numerator and denominator are equal, horizontal asymptote is $$y = \frac{\text{leading coefficient of } P(x)}{\text{leading coefficient of } Q(x)}$$.
Here, degree numerator = degree denominator = 1.
Leading coefficient numerator = 3.
Leading coefficient denominator = 4.
So, horizontal asymptote is $$y = \frac{3}{4}$$.
3. **Vertical asymptote:** Set denominator equal to zero and solve for $$x$$:
$$4x + 14 = 0$$
$$4x = -14$$
$$x = \cancel{\frac{4x}{4}}\frac{-14}{\cancel{4}} = -\frac{14}{4} = -\frac{7}{2}$$
So, vertical asymptote is $$x = -\frac{7}{2}$$.
4. **x-intercept:** Set numerator equal to zero and solve for $$x$$:
$$3x - 7 = 0$$
$$3x = 7$$
$$x = \cancel{\frac{3x}{3}}\frac{7}{\cancel{3}} = \frac{7}{3}$$
So, x-intercept is $$\left(\frac{7}{3}, 0\right)$$.
5. **y-intercept:** Evaluate $$f(0)$$:
$$f(0) = \frac{3(0) - 7}{4(0) + 14} = \frac{-7}{14} = -\frac{1}{2}$$
So, y-intercept is $$(0, -\frac{1}{2})$$.
6. **Hole:** Check if numerator and denominator have common factors.
Factor denominator:
$$4x + 14 = 2(2x + 7)$$
Numerator:
$$3x - 7$$ cannot be factored further.
No common factors, so no hole.
**Final answers:**
- Horizontal asymptote: $$y = \frac{3}{4}$$
- Vertical asymptote: $$x = -\frac{7}{2}$$
- x-intercept: $$\left(\frac{7}{3}, 0\right)$$
- y-intercept: $$(0, -\frac{1}{2})$$
- Hole: None
