IfOne root of the equation x^3-x-1=0 then the equation lies between?

Dear Student

It looks like the options are missing as the result can be expressed in many ways

Please provide us the complete question
Besides ,
You can make graph and use differentiation to observe the roots
Ex- as at x = 1 value is –1 i.e negative while at x= 2 value is positive
so we can say that there is one root is between 1 and 2 but there can be many things to say .
so, it would be better if you provide options available

Thanks
