(See attached file for full problem description with proper symbols and equations)
First: solve this problem.
Second: check my answer.
Third: if my answer is wrong or incomplete explain why.
Explain why cannot have more than one root.
This is how I tried to solve it:
I used the interval [-1,1]
By the Intermediate Value Theorem, since f(0) is between (-1,1), f(0) is the only root.
Please see the attachment.
First, I solve this problem. , . According to the Intermediate Value ...
