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.

C on edge

Step-by-step explanation:

I took the test

i think ur answer is   (3,-1)

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
