Looking for an answer to your question? The domain calculator allows you to take a simple or complex function and find the domain in both interval and set notation instantly. A rational function has a vertical asymptote wherever the function is undefined, that is wherever the denominator is zero. Horizontal asymptote will be $y=0$ as the degree of the numerator is less than that of the denominator and x-intercept will be 4 as to get intercept, we have to make $y$, that is, $f(x)=0$ and hence, make the numerator 0. (An exception occurs . Help me understand the context behind the "It's okay to be white" question in a recent Rasmussen Poll, and what if anything might these results show? A horizontal asymptote (HA) of a function is an imaginary horizontal line to which its graph appears to be very close but never touch. these two terms dominate is that we can divide the The horizontal asymptote describes what the function looks like when x approaches infinity, therefore a = -2 so that the limit of the function as x -> infinity will be -2, So the final answer is f(x). f(x) = [ (x + 2)(x + 3) ] / [ (x + 2) (x - 1) ] What Sal is saying is that the factored denominator (x-3) (x+2) tells us that either one of these would force the denominator to become zero -- if x = +3 or x = -2. What we can do is actually [3] For example, suppose you begin with the function. It looks like f(x) = p(x) / q(x), where both p(x) and q(x) are polynomials. Degree of polynomial in the numerator is 2. Determine the factors of the numerator. Every rational function has at least one vertical asymptote. Since oblique asymptotes have a linear equation, the process is a little different than the horizontal asymptote. Since (x + 2) was striked off, there is a hole at x = -2. Actually let's just do it for fun here just to complete the For Free. It's not defined at negative three and this would be an asymptote right now so we get closer and closer and it could go something like that or it goes something like that.
