Question

find all the points of discontinuity of f defined by f(x)=|x|-|x+1|​

Answer 1

Answer:

Step-by-step explanation:

Start by factoring the numerator and denominator of the function. A point of discontinuity occurs when a number is both a zero of the numerator and denominator. Since is a zero for both the numerator and denominator, there is a point of discontinuity there. Since the final function is , and are points of discontinuity.
