WebSep 7, 2022 · The limit laws allow us to evaluate limits of functions without having to go through step-by-step processes each time. For polynomials and rational functions, \[\lim_{x→a}f(x)=f(a). \nonumber \] You can evaluate the limit of a function by factoring and canceling, by multiplying by a conjugate, or by simplifying a complex fraction.
