Let's analyze the function step by step to determine which graph is correct:
1. Factorization
First, factor the denominator:
So the function can be written as .
2. Asymptotes
Vertical Asymptotes:
Set the denominator equal to zero, , which gives and . So, there are vertical asymptotes at and .
Horizontal Asymptotes:
Since the degree of the polynomial in the numerator (degree ) is less than the degree of the polynomial in the denominator (degree ), by the rules for finding horizontal asymptotes of rational functions, the horizontal asymptote is .
3. Intercepts
x-intercept:
Set , we have , which implies , so . Thus, the -intercept is .
y-intercept:
Set
