## anonymous one year ago Which of the following functions f has a removable discontinuity at a? If the discontinuity is removable, find a function g that agrees with f for x does not equal a and is continuous at a. (a) f(x)= x^4-1/x-1, a=1

factor and cancel is what this is really asking

So the function is: $f(x)=\frac{x^4-1}{x-1}$ correct?
