Which of the following is the inverse of f(x) = 3 – 14x ? A. F-1 (X) = 14 + 35
B. F-1(x) = 3-x/14
C. F-1 (X) = -3/14x
D. F-1(x) = 14+x/3

Hey there! I'm happy to help!

Let's call our fraction x.

x=3.777

We want to get rid of the repeating stuff. If we multiply our fraction by 10, we get 10x=37.7777.

We see that if we subtract x from 10x, the repeating numbers will be cancelled out. Let's do this.

10x=37.7777

-

x=3.77777

=

9x=34

We divide both sides by 9.

x=34/9=3 7/9.

Have a wonderful day! :D
