Show that the equation
Has at least two solutions for x in
Well I ahve found out that the theorem is as follows:
If ƒ(x) is a continuous real-valued function on the closed interval from a to b, then, for any y between the least upper bound and the greatest lower bound of the values of ƒ, there is an x between a and b with ƒ(x) = y
Now how do I apply this to the question.
