Answer:
Overall, the steps for algebraically finding the range of a function are:
1.Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).
2.Find the domain of g(y), and this will be the range of f(x).
3.If you can't seem to solve for x, then try graphing the function to find the range.

Step-by-step explanation:
The number line is a line with marks, where each mark represents a real number.
In the vertical number line zero is in the center. The numbers above zero are considered positive and the numbers below zero are considered negative.
4
3
2
1
0
-1
-2
-3
-4
The numbers after zero start from 0, 1, 2 ...... and 0, -1, -2.....
Hence, Carlos is wrong and -4 is further to zero than -2
Answer:
20 rolls
Step-by-step explanation:
there is 20 in each roll 410/20 is 20.8.
So it is really easy to solve firstly we can see how much does the first 10 boxes make which makes around 55$ obviously. Secondly 45$ for the next 10 boxes.
So for now we can simply calculate that we have spent around 100$ which means 20 boxes. The remaining money left is 77$ so we can buy 77/3.5 = 22 only 22 boxes with that money. Hence a total of 42 boxes.
