Determine the domain of a rational function
WebOct 25, 2024 · Domains of Rational Functions. Set the denominator equal to zero. Solve to find the x-values that cause the denominator to equal zero. The domain is all real … 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.

WebIn general, we can calculate the domain of a rational function by identifying any point where the function is undefined. This means finding any point that makes the denominator equal to zero. To find the range of a rational function, we can identify any point that cannot be reached with any input. This is generally found by considering the ...
WebA vertical asymptote represents a value at which a rational function is undefined, so that value is not in the domain of the function. A reciprocal function cannot have values in its domain that cause the denominator to equal zero.
