Continuity and DifferentiabilityHard

Question

On the interval I = [-2, 2], the function f(x) = 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) = 1
Hence continuous for x ∈ I - {0}
