Answer:
9 4/33.
Step-by-step explanation:
0.12 repeating = 12/99
= 4/33.
Vertical asymptotes ares found where the function is undefined. f(x) is undefined when the denominator equals zero:
x^2-1=0
<em>*Add 1 to both sides*</em>
x^2=1
<em>*Take the square root of both sides*</em>
x=+/-1
There are vertical asymptotes at x=-1 and x=1.
Hope this helps!!
2/a-1 is 100% the correct answer
