The graph of y=f(x)+b can be obtained from the graph of y=f(x) by a vertical translation b units upwards (if b<0, the transformation may also be called a translation ∣b∣ units down).

The graph of y=f(x−a) can be obtained from the graph of y=f(x) by a horizontal translation a units to the right (if a<0, the transormation may also be called a translation ∣a∣ units to the left).

The reciprocal function is defined by f(x)=x1.
Notice that f(x) is not defined for x=0. In fact, since x1 gets very large as x approaches 0, f(x) has a vertical asymptote at x=0.
And since for very large x, x1 approaches zero, there is also a horizontal asymptote y=0.
Notice also that x11=x, so f(x)=x1 is self-inverse.

A linear rational function has the form
When the denominator is zero the graph will have a vertical asymptote:
And as x gets very large, the +b and +d can be ignored:
So there is a horizontal asymptote at y=ca.
