WebPut formally, a real-valued univariate function y= f (x) y = f ( x) is said to have a removable discontinuity at a point x0 x 0 in its domain provided that both f (x0) f ( x 0) and lim x→x0f (x)= L < ∞ lim x → x 0 f ( x) = L < ∞ exist. Another type of discontinuity is referred to as a jump discontinuity. Web7) consider the rational function f (x) = x 2 − 4 x − 12 x 2 − 9 a) Find the vertical asymptotes, if they exist b) Find the horizontal asymptote, if they exist c) Find the x and y intercepts, if they exist D) Sketch a graph of f using the info from part (a) through (c)
Functions
WebThe graph of a function may have several vertical asymptotes. f (x) = has vertical asymptotes of x = 2 and x = - 3, and f (x) = has vertical asymptotes of x = - 4 and x = . In general, a vertical asymptote occurs … WebNow let us look at an example that does cross the horizontal asymptote: f (x) = (x²+2)/ (x²+2x-6) has a horizontal asymptote at f (x) = 1, thus: (x²+2)/ (x²+2x-6) = 1 (x²+2)= (x²+2x-6) 2 = 2x-6 2x = 8 x = 4 Therefore, this function crosses its horizontal asymptote at x=4 Comment ( 22 votes) Upvote Downvote Flag more Jimson Yang 6 years ago origin energy office hours
Quick reminder about asymptotes of piecewise functions
WebSince n < m n < m, the x-axis, y = 0 y = 0, is the horizontal asymptote. y = 0 y = 0. There is no oblique asymptote because the degree of the numerator is less than or equal to the … WebCalculus questions and answers. D. Given f (x)=x2−4x, a) Find the domain b) Find the intercepts c) Find the vertical asymptote d) Find the behavior near vertical asymptote e) Find the horizontal asymptote f) Find the end behaviorg) Find the intervals on which f is increasing or decreasing b) Find the local maximum and minimum values of f. WebFind the vertical, horizontal, and oblique asymptotes, if any, for the following rational function. R (x) = x + 8 9 x Find the vertical asymptotes. Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. A.
