if a is a root of f(x) = e^x + x - 10 by considering dy/dx show there is only one a

OpenStudy (king):

one a?

OpenStudy (anonymous):

My thought exactly. I think it means only one root. It's worded quite badly.

OpenStudy (unklerhaukus):

dy/dx = e^x +1

OpenStudy (anonymous):

How does that show there is only 'one a'?
