Pre Calculus 2 6 Rational Functions Part 2 Youtube A rational function will not have a y intercept if the function is not defined at zero. likewise, a rational function will have x intercepts at the inputs that cause the output to be zero. since a fraction is only equal to zero when the numerator is zero, x intercepts can only occur when the numerator of the rational function is equal to zero. A vertical asymptote represents a value at which a rational function is undefined, so that value is not in the domain of the function. a rational function cannot have values in its domain that cause the denominator to equal zero. in general, to find the domain of a rational function, we need to determine which inputs would cause division by zero.
Precalculus Rational Functions Worksheets 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). A rational function will not have a y intercept if the function is not defined at zero. likewise, a rational function will have x intercepts at the inputs that cause the output to be zero. since a fraction is only equal to zero when the numerator is zero, x intercepts can only occur when the numerator of the rational function is equal to zero.

Example question #4 : rational functions. determine the vertical asymptotes of the following equation: possible answers: there are no vertical asymptotes. correct answer: explanation: first, start by isolating x and y on seperate sides to get the equation into the form of y=x. do this by adding 4x to both sides.
