Which of the following pairs of functions are inverses of each other

 and  

Step-by-step explanation:

Required

The inverse pairs

Solving (a):

Calculate the inverse of f(x)

Replace f(x) with y

Swap x and y

Solve for y

So, we have:

Hence, f(x) and g(x) in (a) are inverse functions

Others are not

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

i would pic false cause it goes down towards negative
