Find the vertical asymptotes if any of the graph of the rati
Find the vertical asymptotes, if any, of the graph of the rational function. h(x) = x + 1/x^2 - 1 f(x) = x/x^2 + 4
Solution
Solution:
Given h(x) = x+1/(x2-1)
We mus set the denominator equal to 0
x2-1 = 0
(x2-12) = 0
(x-1) (x+1) = 0
Therefore x = 1, - 1
There are vertical asymptotes at x = -1, x = 1
2)
Given f(x) = x/(x2+4)
We mus set the denominator equal to 0
x2+4 = 0
x2+22 = 0
(x+2) (x-2) = 0
x = -2,2
There are vertical asymptotes at x = -2, x = 2
