To be continuous at `x=1`, the value of `(x^(4)-1)/(x^(3)-1)` must be defined to be equal to

A

-1

B

0

C

1

D

`(4)/(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Factor and reduce: `((x-1)(x+1)(x^(2)+1))/((x-1)(x^(2)+x+1))`. Substitue 1 for x and the fraction equals `(4)/(3)`.
