1) As we know,
D =
Therefore,
f(0.5) =
= 2.71766
2) As there are no loop in the graph of f(x)= provided below, and as the value of x approaches to zero from negative and positive side it does not shoot to any other value apart from the graph, thus the function is a continuous function.
ii) For a function to be differentiable if, = athen, = aTherefore, the above expression for 0 would become,
Expanding using Taylors series,
As we can see that,
The given function is differentiable.
