Question

Marie is logging the number of radioactive isotopes she observes every minute. She has determined her function to be f(x) = −4x + 120.

Based on the situation above, describe any necessary restrictions to the domain and range. Provide justification for the restrictions.

Answer 1

It wouldn't make sense to have a negative number of isotopes, so x cannot be greater than 30. The range would be 0 to 120.

Answer 2

so the range is o to 120. what about the domain?

Answer 3

This is better .
The function is defined as is. You cannot disagree with a clearly defined function. All you have to do is concentrate on figuring out the domain and range. The domain is all the x values that represent the number of minutes elapsed The range is all the y values that represent the number of radioactive isotopes remaining in terms of minutes elapsed.

Answer 4

you just got that from hero. i already sow that but i dont know the domain and the restrictions?

Answer 5

yeah , i did ! be grateful its some type of help !

Answer 6

not really because I already seen that before i posted this. and im still confused so i guess it was no help

Answer 7

dont be getting smart ! & YEAH IT IS SOME TYPE OF HELP ! did i know you saw it ? NO ! Therefore , be thankful !

Answer 8

you probably dont know anything about math. you probably just copy and paste someones question into google and copy and paste someone elses answer to make you feel like your helping someone and so that you can get points. what a shame

Answer 9

NAH ! i know alot thankyou very much ! you ungrateful a*s ! YOU SHOULD B ASHAMED OF YOURSELF TRYNA GET BUKK ! THIS IS THE ONLY THING I "COPIED & PASTED" keep yo mouth shut !

Answer 10

first of all my mouth has bin shut the whole time, im just moving my fingers lol but i doubt that this is the only thing you copied and pasted because you posted it so fast as if you do it all the time. if you know abou math you should help people yourself and not act like you know about math by copy and pasting other people who actually know about math ansers.

Answer 11

THERE YOU GO AGAIN ! IM FAST B KAUSE I ANSWER ONE QUESTION THEN GO ON TO THE NEXT ? NAH THATS KALLED HARD WORK ! I GOT A 97% IN MATH THANKYOU VERY MUCH ! YALL THINK SOMEONE ALWAYS KOPYING & PASTING WHEN THEIR JUST FAST WORKERS ! GTFOH WIT THAT BS !

Answer 12

i KNOW YOUR TYPING BUT I DNT NEED YOUR INPUT ! JUST MOVE ON...

Answer 13

its not hard work when you just copy and paste someone elses (hard work) answers. i just dont get why you sit there on your computer and just google peoples questions and copy and paste other peoples answers. why do you do that? to make you feel good ? to make you feel smart? you got nothing els to do? ok im done

Answer 14

YEAH B DONE ! I DONT GOOGLE EVERYBODYS STUFF , IT WAS JUST THIS ONE ! IM PRETTY SURE YOU DO THE SAME THING ! BYE !
