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:

Step-by-step explanation:
Let
be the length of the longer side of the smaller rectangle and
be the length of the shorter side of the smaller rectangle
When you look at the combined rectangle from top to bottom, you can see that
. Therefore, 
This is the same for
. Thus, 
When you look from right to left, you can see that
. Using this, we can represent
in terms of
.

Now, we can find the ratio of
