Question

Find the vertical asymptotes, if any, of the graph of the rational function: h(x) = (x - 1) / (x2 + 1)

Expert Solution
Step 1

The line x=L is a vertical asymptote of the function y=x1x2+1, if the limit of the function (one-sided) at this point is infinite.

In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.

So, find the points where the denominator equals 0 and check them.
