Which two functions are inverses of each other?
f(x)= x, g(x) = -x
f(x)= 2x, g(x) = - 1/2x
f(x) = 4x, g(x) = 1/4x
f(x) = -8x, g(x) = 8x

Option 3 - f(x)= 4x,

Step-by-step explanation:

To find : Which two functions are inverses of each other?

Solution :

Two functions are inverse if

Now, we find one by one

1) f(x)= x, g(x) = -x

Not true.

2) f(x)= 2x,

Not true.

3) f(x)= 4x,

i.e. is true.

So, These two functions are inverse of each other.

4) f(x)= -8x,

Not true.

Therefore, Option 3 is correct.

Step-by-step explanation:

I took the test

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
