Rational Functions A function f represented by where p(x) and q(x) are polynomials and q(x) ≠ 0, is a rational function. Rational Function The domain of a rational function includes all real numbers except the zeros of the denominator q(x). The graph of a rational function is continuo...
Simplifying Rational Functions In order to understand how to simplify rational functions, it is pertinent to understand the vocabulary around this concept. Relevant terms to become familiar with include polynomials, rational function, rational expression, factors, and factorization. ...
or the sum of a sine and a cosine functions. 2. When the frequency Ω0=0, we get that the inverse Laplace transform of X(s)=a+b(s+α)(s+α)2=a(s+α)2+bs+α(corresponding to a double pole at -α) is x(t)=limΩ0→0aΩ0e-αtsin(Ω0t)+be-αtcos(Ω0t)u(t)=[...

polynomial functions, here to we must test each side of the vertical asymptote to see what the function does. Example 3: In example 1 we found two vertical asymptotes for the function 25 1 2 x x f , which were x = -5 and x = 5. Determine what this function does on each si...
