I don't entirely understand the question which is why I am posting it here. Anyways, from what the question is asking;we are trying to find the removable discontinuity. This would be plugging in x=0 into both equation and combining them. When this is applied to the first equation, the answer is 0. For the second one, it is 7. So, when the question asks me to combine them, I really don't know what to do with the values. Please Help! I would really appreciate it.
