Determine the domain of a rational function
WebJul 16, 2024 · In simple terms: The domain of a rational function is the set of inputs (x-values) that do not cause a zero denominator. For example, the domain of f (x) = 1/x is all real numbers except x = 0, often denoted as R – {0}. The range of a rational function is the set of all possible outputs (y-values). For example, the range of g (x) = 1/x 2 is ... WebOct 3, 2024 · To find the domain of a rational function set the denominator to zero and solve for x. Then, write out the answer in either set or interval notation, ensuring to exclude the values of x that make ...

WebSep 5, 2024 · Rational function, \(\ f(x)=\frac{x}{x-6}\) Rational functions may seem tricky. There is nothing in the function that obviously restricts the range. However, rational functions have asymptotes: lines that the graph will get close to, but never cross or even touch. In the graph above, the domain restriction provides one asymptote, \(\ x=6\).
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. ching yern cheeWebExample Problem 1: Finding the Domain and Range from a Graph of a Rational Function.
