Taylor theorem

Homework Statement


f(x) = (1+x)^(1/3)
Use taylor's theorem to write down an expression for the error R_3(x) = f(x) - P_3(x). In what interval does the unknown constant c lie?

I cant find what value is x where c lies between x and a.

Homework Equations


in previous question, we are required to find 6^(1/3) by doing 2(1- 1/4)^(1/3)


The Attempt at a Solution



i got a= 0 and c must lie between a and x.
and R_3(x) = 10x^4/[243(1-x)^(11/3)]

i know the first boundary of c must be zero but i cant find the other boundary
