Set each factor in the denominator equal to zero and solve for the variable. If this factor does not appear in the numerator, then it is a vertical asymptote of the equation. If it does appear in the numerator, then it is a hole in the equation. In the example equation, solving x –...
To find a slant (or oblique) asymptote, long-divide the numerator by the denominator; ignore the remainder. The polynomial part is your asymptote.
To find a vertical asymptote, first write the function you wish to determine the asymptote of. Most likely, this function will be a rational function, where the variable x is included somewhere in the denominator. As a rule, when the denominator of a rational function approaches zero, it has...
Step 2:Find all vertical asymptotes. A vertical asymptote is a vertical line {eq}x = c {/eq} that the graph of the function cannot touch. The graph will instead get closer to this line, but either go up or down infinitely and never touch the line. ...
it has a vertical asymptote. Once you've written out your function, find the value of x that makes the denominator equal to zero. As an example, if the function you're working with is y = 1/(x+2), you would solve the equation x+2 = 0, an equation which has the answer x = ...
Find the horizontal asymptote of .Now that I know the rules about the powers, I don't have to do a table of values or draw the graph. I can just compare exponents. In this rational function, the highest power in each of the numerator and the denominator is the same; namely, the ...
How to find horizontal asymptotes (2x - 3) / (x - 4)? Determine the vertical asymptote(s) a) f(x) = x + 2 / x^3 - 6 x^2 + 8 x b) f(x) = x + 3 / x^3 - 3 Find the vertical and horizontal asymptotes of \frac{2x^{2} + 7x + 12}{x^{2} - x - 2} ...
Example 1:To find the domain of a function f(x) = √(x + 3), we apply the rule 2 mentioned above. Then we get: x + 2 ≥ 0. Solving thisinequality, we get x ≥ -2. Thus, the domain of f(x) is [-2, ∞). Example 2:To calculate the domain of a function g(x) = (...
How do you find the limit of a function? To find the limit of a function, use either the direct substitution or factoring method. Direct substitution is best when there is no break, jump, or vertical asymptote at the set value c. It involves substituting the value c for x in the fu...
