Finding domain of a rational function
WebTo find the domain of a rational function: Take the denominator of the expression. Set that denominator equal to zero. Solve the resulting equation for the zeroes of the denominator. The domain is all other x -values. Find the domain of \small { \color {green} {\boldsymbol { \dfrac {3} {x} }}} x3 The domain is all values that x is allowed to be. WebThe Domain The domain of a rational function is found using only the vertical asymptotes. As previously noted, rational functions are undefined at vertical asymptotes. The rational function will be defined at all other x values of the domain. ()x ( )( )2 3 x f x x = + − Here is a rational function in completely factored form. x and x=− =2 3

WebSep 30, 2024 · Rational Functions. Rational functions are defined as the ratio of two polynomial expressions. For example, suppose we're given two simple linear polynomial functions: f 1 = 10x + 6 . f 2 = x - 1 ... WebAnswer. Remember that a rational function is only defined when its denominator is nonzero. Therefore, to find the domain, we need to find the zeros of the equation 1 0 𝑥 + 7 0 𝑥 = 0. To solve this, we can factor out an 𝑥 to get 𝑥 1 0 𝑥 + 7 0 = 0. . From here, we can see that we have a zero when 𝑥 = 0.
