Question

How do I find the removable discontinuity of the rational function shown in the image?

Answer 1

Answer:

x = +1

Step-by-step explanation:

A hole is formed when the function becomes undefined at a point. This can occur if the numerator and denominator is equal to 0

Here x^2 - 1, equating it to 0

x^2 = 1

x = +1,-1

Numerator is also 0 at x = +1

So we have a hole at x = +1.
