Let's analyze the function $$ f(x) = \frac{-2x^2 - 2x + 4}{2x + 1} $$ step by step to find the required characteristics.

### a. Vertical Asymptote(s) Equation:
To find the vertical asymptote, we set the denominator equal to zero:
$$
2x + 1 = 0 \implies x = -\frac{1}{2}
$$
**Vertical Asymptote:** $$ x = -\frac{1}{2} $$

### b. End Behavior Asymptote Equation:
For rational functions, if the degree of the numerator is greater than the degree of the denominator, there are no horizontal asymptotes. In this case, the degree of the numerator (2) is greater than the degree of the denominator (1).
**End Behavior Asymptote:** No horizontal asymptotes.

### c. $$ x $$-intercept(s):
To find the $$ x $$-intercepts, we set the numerator equal to zero:
$$
-2x^2 - 2x + 4 = 0
$$
Factoring or using the quadratic formula gives us:
$$
x_{1} = -2, \quad x_{2} = 1
$$
**$$ x $$-intercepts:** $$ x = -2 $$ and $$ x = 1 $$

### d. $$ y $$-intercept:
To find the $$ y $$-intercept, we evaluate $$ f(0) $$:
$$
f(0) = \frac{-2(0)^2 - 2(0) + 4}{2(0) + 1} = \frac{4}{1} = 4
$$
**$$ y $$-intercept:** $$ 4 $$

### e. Coordinate of Hole:
A hole occurs when a factor cancels in the numerator and denominator. In this case, there are no common factors, so there is no hole in the function.
**Coordinate of Hole:** None

### f. Domain:
The domain of the function is all real numbers except where the denominator is zero:
$$
f(x) \in \mathbb{R} \text{ except } x = -\frac{1}{2}
$$
**Domain:** $$ x \in \mathbb{R}, x \neq -\frac{1}{2} $$

### g. Range:
The range of the function is all real numbers since the function can take any value as $$ x $$ approaches the vertical asymptote.
**Range:** $$ f(x) \in \mathbb{R} $$

### Summary:
- **Vertical Asymptote:** $$ x = -\frac{1}{2} $$
- **End Behavior Asymptote:** No horizontal asymptotes
- **$$ x $$-intercepts:** $$ x = -2 $$ and $$ x = 1 $$
- **$$ y $$-intercept:** $$ 4 $$
- **Coordinate of Hole:** None
- **Domain:** $$ x \in \mathbb{R}, x \neq -\frac{1}{2} $$
- **Range:** $$ f(x) \in \mathbb{R} $$
- **Vertical Asymptote:** $$ x = -\frac{1}{2} $$ - **$$ x $$-intercepts:** $$ x = -2 $$ and $$ x = 1 $$ - **$$ y $$-intercept:** $$ 4 $$ - **Domain:** All real numbers except $$ x = -\frac{1}{2} $$ - **Range:** All real numbers
