Question
x² + x-20
5x +9
Identify roots and asymptotes
x2 + x – 20
5x +9
has root(s) at I =
x2 + x – 20
has vertical asymptote(s) at x =
5x + 9
x² + x – 20
will be non-zero:
Use interval notation to represent the four separate intervals where
5x +9
Type "inf" and "-inf" for 00 and -00, respectively.
Type the capital letter "U" to represent the union symbol U.
