The integral is .
(a)
\Graph :
\Graph the function is .
(b)
\Observe the graph :
\The graph of the function approaches to as
tends to
but not equal to
.
Hence the function has a horizontal asymptote at .
The function has non-removable discontinuity at as the value of the function oscillates between
to
.
