1.What a rational function?Do you remember what a polynomial function is?If you know a function of the form is a form as following f(x)=an xn+an-i xn-1+…+a1x+a0,where an,an-i,…a1,a0are real numbers and n is nonnegative integer.The domain of a polynomial function is the set of all real numbers.But here are
1. What a rational function?
Do you remember what a polynomial function is? If you know a function of the form is a form as following f(x)=anx^n+an-ix^n-1+… a1x+a0 ,
