Part C: Horizontal asymptote is 
Part D: Range is 
Explanation:
Part A: We need to determine the vertical asymptote
The vertical asymptote of a function can be determined by equating the denominator equal to zero.
Thus, we have,

Hence, the vertical asymptote is 
Part B: We need to determine the domain
The domain of the function is the set of all independent x - values for which the function is real and well defined.
Let us take the denominator and equate to zero.
Hence, we have, 
Therefore, the function is undefined at the point 
Thus, the domain of the function is 
Part C: We need to determine the horizontal asymptote
The horizontal asymptote of the function can be determined by dividing the leading coefficient of the numerator by leading coefficient of the denominator.
Thus, we have, 
Hence, the horizontal asymptote of the function is 
Part D: We need to determine the range
The range of the function is the set of all dependent y -values of the function.
In other words, the range of the function can be determined by substituting the values for x.
Thus, we have,

Therefore, the range of the function is
