Answer:
The last one is the answer.
Answer:
B.
Step-by-step explanation:
-5/-7×-11/-6
= (-5 * -11) / (-7*-6)
= 55 / 42.
A. = - (6/-11) = 6/11
-5/7 * 6/11 = -30/77.
B. - (-11/7) = 11/7
5/6 * 11/7
= 55/42.
will be increasing on the intervals where
and decreasing wherever
. Local extrema occur when
and the sign of
changes to either side of that point.
is positive when
is between -4 and some number between -2 and -1, and also 2 (exclusive) and 4, so you can estimate that
is increasing on the intervals [-4, -2] and (2, 4].
is negative when
is between some number between -2 and -1, up to some number less than 2. So
is decreasing on the interval [-1, 1].
You then have two possible cases for extrema occurring. The sign of
changes for some
between -2 and -1, and again to either side of
.
