I think there is one discontinuity
Hey! In order to find the discontinuity you have to plug in the end points of the intervals to both equations. For example, you would plug in -3 to both the first and the second equation, and see if they are equal. If they aren't equal, then there is a discontinuity.
plug in -3 in for x? @steve816
Yup! To the first and second equation.
