Explanation:
This function is decreasing when the y-value decreases.
In interval notation this is written as so:
Dec(
The
The function also decreases at the end as x approaches positive infinity.
This function is decreasing in the intervals
Explanation:
A function
f(x) > f(a) for allx in (a-epsilon, a)
f(x) < f(a) for allx in (a, a+epsilon)
If the function has a well defined tangent at the point
In the given example, note that for any

Given that the function has vertical asymptotes at
y = 2/((x-1)(x+1)) = 2/(x^2-1)
graph{2/(x^2-1) [-10, 10, -12, 12]}
