Question
On the interval I = [-2, 2], the function f(x) = 
then which one of the following hold good ?
then which one of the following hold good ?Options
A.is continuous for all values of x ∈ I
B.is continuous for x ∈ I -(0)
C.assumes all intermediate values from f(-2) & f(2)
D.is continuous for x ∈ I -(0)
Solution
(x + 1) e-[2/x] = 
= 0
(x + 1) 
= 1Hence continuous for x ∈ I - {0}
