)
from
x
=

to
x
=
t
and evaluate it for
t
=

3.
(1 pt) Determine whether the integral is divergent or con
vergent. If it is convergent, evaluate it. If it diverges to inﬁnity,
state your answer as ”INF” (without the quotation marks). If it
diverges to negative inﬁnity, state your answer as ”MINF”. If
it diverges without being inﬁnity or negative inﬁnity, state your
answer as ”DIV”.
