RATIONAL FUNCTIONS
Goal:
­ to recognize the two forms of any rational function:
­ standard form
­ general form
­ to convert from one form to another
1
What is a rational number?
So what might a rational function look like?
2
The standard form for the rule of any rational function is:
which can be simplified to:
3
The general form of the rule for a rational function is:
4
How can we convert between the forms?
standard
general
5
Ex: Convert:
a) f(x)=3/2x­4+1 to general form
6
b) f(x)=(4x+3)/(2x­1)
