Answer:
(-infinity, 4]
Step-by-step explanation:
The range is the possible y values
The smallest that (x+3)^2 can be is zero
f(x) = 4 − 2(x + 3)^2
f(x) = 4 -2(0) = 4
This is the maximum value
As the square term gets bigger we are subtracting a larger amount and it will get more negative
Let x = infinity, x+3 = infinity and infinity ^2 = infinity and 2* infinity = infinity
f(x) = 4 - infinity
= -infinity
The range is -infinity to 4
Answer
<h2><u><em>
3 boxes</em></u> </h2>
Step-by-step explanation:
So she needs to give 25 pencils to each student.
1 box = 12
number of boxes = 25/12
=2.08
round it to 3
<h2><em>
Therefore she need </em><u><em>
3</em></u><em>
boxes</em></h2>

81,27, 9, 3, 1 just guess
Step-by-step explanation:
7 + x/3 =2x - 5
7 + 5=2x - x/3
12 = 5x/3
cross multiply
36=5x
x=36/5
x=7.2
