Similarly, horizontal asymptotes occur because y can come close to a value, but can never equal that value. ... Thus, f (x) = has a horizontal asymptote at y = 0.Horizontal Asymptotes and Slant Asymptotes of Rational Functions15 related questions found How do you identify a horizontal ...
The horizontal asymptote of a rational function can be determined by lookingat the degrees of the numerator and denominator. Degree of numerator is less than degree of denominator: horizontal asymptote at y = 0. Degree of numerator is greater than degree of denominator by one: no horizontal asym...
Graph the rational function f(x)=(-6)/(x-6)To graph the function, draw the horizontal and vertical asymptotes (if any) and plot at least two point the graph. 相关知识点: 试题来源: 解析 x-6=0 x=6 vertical asymptote at x=6 horizontal asymptote at y=0 ...

in the numerator, then the graph trails along thex-axis at the far right and the far left of the graph. So any time the power on the denominator is larger than the power on the numerator, the horizontal asymptote is going to be the thex-axis, also known as the liney= 0. ...
The Bode plot for low frequency regions is, for magnitude, a horizontal asymptote crossing ωp at 0 dB and for phase, a horizontal asymptote of 0°. If the high frequency region is analyzed, the magnitude and the phase of the transfer function become (12)ω≫ωp⇒{|H1p(ωj)|dB=...

f(a)=0 D. None of the above 相关知识点: 试题来源: 解析D If y=a is a horizontal asymptote of the function y=f(x), then EITHER limlimits _(x→ ∞ )f(x)=a OR limlimits _(x→ -∞ )f(x)=a. Because either of these is sufficient for a horizontal asymptote at y=a, (A)...
Remember that an asymptote is a line that the graph of a function approaches but never touches. Rational functions contain asymptotes, as seen in this example:In this example, there is a vertical asymptote at x = 3 and a horizontal asymptote at y = 1. The curves approach these asymptotes ...
