What value must be defined for f(4) to remove the discontinuity of this function at x = 4?
f(x)= x^216/x4
0
4
4
8
8

for x ≠ 4, f(x) = x+4
so, f(4) = 8 to fill in the removable discontinuity.

A function f(x) is said to have a removable discontinuity at x=a if: 1. f is either not defined or not continuous at x=a. 2. f(a) could either be defined or redefined so that the new function IS continuous at x=a. Let f(x)=2x^2+3x–14/x–2 …
