Question

**please Help me**
The formula C=(5/9)(F−32), where F>=−459.67 expresses the Celsius temperature C as a function of Fahrenheit temperature F.
Find the inverse function and the domain of the inverse function.

Answer 1

i found the inverse function to be (1/5)(9F+160) but i can't get the domain

Answer 8

i tried that

Answer 9

it was wrong

Answer 10

the -infinity part is wrong

Answer 11

?

Answer 12

i'm confussed

Answer 13

so what would the domain be

Answer 14

the lowest temperature, I think. in your case it is -459.67

Answer 15

i've tried that too

Answer 16

[-459.67,infinity) is wrong

Answer 17

so your interval is from [-459.67, +infinity)

Answer 18

it's wrong? lol then i don't know

Answer 19

yeah it says it is

Answer 20

there are two infinities though - and +

Answer 21

the domains i've tried are (-infinity,infinity) and [-459.67,infinity) and (-459.67,infinity)

Answer 22

well that's because we are using F temperature. convert F>=−459.67 into celsius and use that as your beginning interval

Answer 23

ok

Answer 24

let me know if that's wrong still … LOL

Answer 25

i tried doing what u said and got (-273.15,infinity). it said the type of interval was wrong. what does that mean

Answer 26

Answer 27

I am here

Answer 28

don't use ( use [

Answer 29

ok thanks i got it right.

Answer 30

you're welcome

Answer 31

every time you see greater than or equal to and lesser than or equal to it is always [ or ]
only with infinity that you use ( or ) because we can never really reach infinity
