How do you find the domain, identify any horizontal, vertical, and slant (if possible) asymptotes and identify holes, x-intercepts, and y-intercepts for #(x^2-1)/(x^2+4)#?
H.A. = 1
V.A. = non
S.A. = non
. Domain is all real numbers
.When the degree of denominator is equal to the degree of nominator,
.For rational functions, V.A. are the undefined points (zeros of the
denominator) of the simplified function.
. There are no slant asymptote because there is no V.A.
.There are no holes because there are no common factors in the
nominator and the denominator
solve using quadratic formula
