Use the precise definition of a limit to prove the limit. Specify a relationship between ? and ? that guarantees the limit exists.x4 = 16
A. ? = min; Let ? > 0 and assume 0 <
< ?. Then
=
=
That is, for any ? > 0,
= ? whenever 0 <
< ?, provided 0 < ? ?
. Therefore,
x4 = 16.
B. ? = min; Let ? > 0 and assume 0 <
< ?. Then
=
=
That is, for any ? > 0,
= ? whenever 0 <
< ?, provided 0 < ? ?
. Therefore,
x4 = 16.
C. ? = min ; Let ? > 0 and assume 0 <
< ?. Then
=
<
That is, for any ? > 0,
< ? whenever 0 <
< ?, provided 0 < ? ?
. Therefore,
x4 = 16.
D. ? = min ; Let ? > 0 and assume 0 <
< ?. Then
=
<
That is, for any ? > 0,
< ? whenever 0 <
< ?, provided 0 < ? ?
.
Therefore, x4=16.
