as "x" approaches infinity and "y" approaches 0 for the function "y=1/x" — "y=0" is the horizontal asymptote. You can save time in finding horizontal asymptotes by using your TI-83 to create a table of "x" and "y" values of the function, and observing trends in ...
解析 B。本题考查函数的渐近线。选项 A,y = 2x 没有水平渐近线;选项 C,y = x + 2 没有水平渐近线;选项 D,y = 2^x 当 x 趋于负无穷时,y 趋于 0,没有水平渐近线;只有选项 B,当 x 趋于无穷时,1/x 趋于 0,y = 2 + 1/x 趋于 2,有水平渐近线 y = 2。

There are three types of asymptotes in a rational function: horizontal, vertical, and slant. Horizontal asymptotes are found based on the degrees or highest exponents of the polynomials. If the degree at the bottom is higher than the top, the horizontal asymptote is y=0 or the x-axis. If...

If n = m, the horizontal asymptote is y = a/b. If n > m, there is no horizontal asymptote. How many horizontal asymptotes can there be? A function can have at most two different horizontal asymptotes. A graph can approach a horizontal asymptote in many different ways; see Figure 8 in...
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 ...
