Hi I know its a lot of rate of change I just don't understand

Which of the following pairs of functions are inverses of each other? o a. f(x)=x72+8 and 96-9 = 7/x+2) =8 o b. f(x)= 6(x - 2)+3 and g(x) - *#2-3 o c. $4) = 5(2)-3 and 90- 4*: 73 o d. f(x) = 6)-12 and 910 – +12

Add the fractions, and simply the result to lowest terms. 2/3 + 2/7= ?

What is the inverse of f(x) = 6x -24
