Your Welcome!!

No problem and thanks! Yes, these questions are tricky in their wording! 

oh okay!Thanks for that AzizHusain!At least somethings got in my brain!lol!

This question sounds really confusing i think i'll have to read the question and the answers a number of times to get the right thing!

But thanks once again!Thumbs up from me!

This question is using rectangles to represent the domain and range of a function. In this case, the perimeter is the function we are interested in and we have to plug in values for w to find the range of the function. It may be easier to think of it in terms of {} since the table form has a lot going on.

Thanks for the points DS!

I havent heard of a question like that before!Can anyone pls expalin me what the question means or exactly says , its all going above my head!!

The number 1.6 X 10^-19 sounds very familiar...it is not the gravity one but Coulomb's Law! Force = Coulomb constant X charge on one item X charge on another item and finally divide it by the distance between the items squared!

Okay. Bye.

Yes, it was, but I like to write anyway. 

That was a detailed answer!

No problem. 

That's okay. But thanks.

I apologize for my errors! I got carried away with just "range."

The answer is 1.6850581551. You find the answer by multiplying the base by the power. (1.11) is the base, and the 5th power is the power.

Hope it helps!

Okay. Thanks.

Wait...I made a critical mistake...

It asked for the range of the function and not just range, so the range of the function would be the values of 4w + 6w so {10,20,30,40,50}.

Happy to help. 

Thank you! I never knew that there was a formula for the functions! Thank you, thank you, thank you, very much! I really needed that. Thanks!

Oh, in this case, you obtained values by calculating the perimeter as the variable, w, varied. You would have different numbers in different questions and they could be 500,499, 100 or just 1, 1, 3. 

The general formula for the range is always: highest value - lowest value.

Suppose, there was w = 6, then the range would change since w = 5 would not produce the highest value anymore.

Oh, So in every problem, the number equals 10, 20, 30 40 and 50. I now get it. Thanks. AzizHusain, can you tell me what is the formula for the range of functions?

The range is a math term that basically states that you take the highest number you get and subtract it from the lowest number. It is often asked for along with mean, median, and mode, and is used a lot in statistics as well. For example, if you have a set of numbers {1,3,5}, the range will be 5 -1. In this case, you are already given the numbers so no calculations are necessary. The mean would be 3, median 3 as well, etc.

AzizHusain, I don't get the part which you say that the range is the largest value minus the smallest value --> 50 - 10 = 40.

May you please explain that a little further please?

No problem. 

Thank you, AzizHusain. Thank you!

We have the perimeter equation, P = 4w + 6w. So, all we have to do is calculate the perimeter as w increases by 1 each time from a value of 1 to 5.

The range is the largest value minus the smallest value --> 50 - 10 = 40.
