Given:
The rational function is defined by .
Result used:
Vertical asymptote:
Consider a rational function , in its lowest terms. If ris a real zero of the polynomial q(x), then x = r is a vertical asymptote of the function R.
Horizontal or oblique asymptotes:
Consider a rational function where nis the degree of the polynomial p(x) and mis the degree of the polynomial q(x). If , the rational function R has no horizontal asymptote and only has an oblique asymptote given by where is quotient obtained by the polynomial division .
Calculation:
Rewrite the rational function as follows.
Hence, the rational function in its lowest terms is .
The polynomial in the denominator of is 1 and 1 has no zeros.
Therefore, the rational function has no vertical asymptote.
Note that, the degree of the polynomial in the numerator is 2 and the degree of the polynomial in the denominator is 1.
That is, the degree of the polynomial in the numerator is 1 more than the degree of the polynomial in the denominator.
Therefore, the rational function has no horizontal asymptote.
The polynomial division gives the quotient as 2x +7.
Therefore, the rational function has an oblique asymptote given by .
Hence, the rational function has no vertical asymptote, no horizontal ext and oblique asymptote is .
