Rational Functions:
Domain: all real numbers except what makes the denominator equal
zero
Y-intercept: at f(0)
X-intercept: zeros of the numerator that are NOT zeros of the
denominator
Vertical asymptote: at x=c iff c is a zero of the denominator but NOT
Find the Asymptotes and the holes for the following:
1.
VA: x = 4
HA: y = 1
Hole at -2
2.
VA: x = 7, x = 1
Asymptote: y = 2x + 14
No holes
3.
VA: x = 1
Asymptote: y = x
No holes
4.
VA: x = 3
Asymptote: y = x + 6
Hole at 4
5.
VA: x = -1
HA: y = 0
Hole at 0
