Which two functions are inverses of each other? a. f(x) = x, g(x) = –x b. f(x) = 2x, g(x) = -1/2x c. f(x) = 4x, g(x) = 1/4x d. f(x) = –8x, g(x) = 8x

The correct option is C)

Step-by-step explanation:

We need to find out the pair of functions which are inverse of each other

A)

  Since,

   and      

So, these are not inverse of each others

B)

  Since,

   and      

So, these are not inverse of each others

C)

  Since,

   and      

So, these are inverse of each others

D)

  Since,

   and      

So, these are not inverse of each others

Therefore the correct option is C)

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.

.25 times 180= 45
