Question

I need help *** if someone can get back to me you will get a medal!! really need help lost

Answer 1

Post the question you need help with, and not an advertisement to "swap answers" please

Answer 2

what quiz

Answer 3

ok for the function 32 over x+3 find (g^-1*g(5)

Answer 4

Graphing Radical Functions Quiz
'

Answer 5

what is the value of g(5)?

Answer 6

Sorry it soupposed to be (g^-1*g)(5)

Answer 7

I dont remeber that, srry I take Geometry and Id ont rmeber how to solve

Answer 8

it does not say what g equals

Answer 9

im pretty sure g is the name of the function they gave you

Answer 10

\[g(x)=\frac{32}{x+3}\]

Answer 11

ok so i multiply that funtion by itself to the -1 power?

Answer 12

the -1 notation here denotes the inverse of the function .. not really a power

Answer 13

do you know how to find an inverse?

Answer 14

not really

Answer 15

given a function
\[y=\frac{32}{x+3}\]
the inverse swapps x and y, so the inverse of this is
\[x=\frac{32}{y+3}\]

Answer 16

so now i divide?

Answer 17

lets work the inverse a little more .. just so things loook normal

\[x=\frac{32}{y+3}\]
\[y+3=\frac{32}{x}\]
\[y=\frac{32}{x}-3=g^{-1}(x)\]

Answer 18

so, \[g^{-1}*g=(\frac{32}x-3)(\frac{32}{x+3})\]
plug in x=5 and find the product

Answer 19

4

Answer 20

now what? would i times 4 by 5?

Answer 21

not if your following what ive written ....

Answer 22

the answer choices are 11 5 2 and 1 so ???

Answer 23

what now

Answer 24

sorry i am not good at this

Answer 25

hmm, you sure thats a "*" in between them or is it more of an "\(^o\)"

Answer 26

an o

Answer 27

ahhh, that changes things, the open "o" means a composite, not a multiplication of the 2 of them

Answer 28

g^(-1) o g has a property that the input is the same as the output

Answer 29

could you check out the math chat box it may need to be controlled.

Answer 30

it needs the adminstrators to come online and deal with the isp itself .. so that the whole school gets banned

Answer 31

so if the input is 5, what is the output?

Answer 32

5?

Answer 33

-5

Answer 34

yes, if the input is 5, the output is 5 ... its a special property of composing inverses of each other

Answer 35

what school. Cant you bn them if they need

Answer 36

so if there is an o don't multiply make input sam as output?

Answer 37

only if the functions are inverses of each other does that work. If they are not inverses the input and output can be different

Answer 38

Answer 39

good luck ::)
