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)#?
1 Answer
Domain =
H.A. = 1
V.A. = non
S.A. = non
No Hole
x-int =
y-int =
Explanation:
. Domain is all real numbers
.When the degree of denominator is equal to the degree of nominator,
H.A.=
.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
