Please my answer is wrong help

We consider the function when moving from left to right.  So the first part, from x = -∞ to -2, is decreasing.  The next part from -2 to 3 (exclusive) is constant.  The last part, from 3 to ∞, is increasing.

(a)

A.   The increasing interval is [3, ∞).  

The bracket means 3 is included in the interval, closed on that side.  It's open on the infinity side; infinity itself isn't really a number so not included in the range.

I'll guess the rest is:

(b)

Constant on the interval (-2,3).

That interval is open on both ends, so doesn't include -2 or 3.

(c)

Decreasing on the interval (-∞, -2].

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:

24+4=28

28/4=7  

the answer to this is 4340

hope this if needed hmu
