In each of the following, find the value of the constant k so that the given function is continuous at the indicated point :
at x = 2.
Given:
f(x) is continuous at x = 2 & f(2) = k
If f(x) to be continuous at x = 2,then,f(2)– = f(2) + = f(2) LHL = f(2)– = 
(a–b)3 = a3–b3–3a2b + 3ab2
(a–b)2 = a2–2ab + b2

Since ,f(x) is continuous at x = 2 & f(2) = k
k = 7
