i) The given function is
We factor to obtain
The domain is
ii) The vertical asymptotes are
iii) To find the root, we equate the numerator to zero.
iv) To find the y-intercept, put x=0 into the function.
vi) To find the horizontal asymptote, we take limit to infinity.
This implies that;
The horizontal asymptote is y=0.
vii) The numerator and the denominator do not have common factors that are at least linear.
Therefore the function has no holes in it.
