I have a question if someone has a few minutes to explain it to me.
I am going over my practice test and one of the questions if the thread title. I am unsure if I understand what it is asking. Does it want what the bounds are that the real zeros will be in?
The function is x^5+2x^4+2x^3-7x^2+x+4
According to the test, the answer is -8 and 8 but I have no idea how to get there. Looking at the graph of the function, I would think it would fall between -1 and 1, but again, I am unsure as to what it is asking for when asking for the bounds.
Our instructor missed class the other day so we have not went over this and I am trying to stay ahead.
