WebOct 2, 2024 · A rational function is a function which is the ratio of polynomial functions. Said differently, r is a rational function if it is of the form. r(x) = p(x) q(x), where p and q are polynomial functions. a. a According to this definition, all polynomial functions are also rational functions. (Take q(x) = 1). WebA rational function will have a y-intercept when the input is zero, if the function is defined at zero. A rational function will not have a [latex]y[/latex]-intercept if the function is not defined at zero. Likewise, a rational function will have [latex]x[/latex]-intercepts at the inputs that cause the output to be zero.
