Question

Does anybody know how to do the inverse of a function? work attached

Answer 1

Match the function (f) with its inverse (f-1).
f(x)= 3x + 1

Answer 2

answer choices are
3x-12
3x+12
f(x)-1=x-3/3
x-1/3
this funtion does not have an inverse

Answer 3

suppose you wanted to solve \(3x+1=7\) for \(x\)
what would you do?

Answer 4

subtract 1 from both sides

Answer 5

right
then ...

Answer 6

divide by 3

Answer 7

exactly

Answer 8

that is what the inverse function does: subtract 1, divide by 3
you can write it as \(f^{-1}(x)=\frac{x-1}{3}\)

Answer 9

so the answer for #1 is D

Answer 10

has the same answer choses
f(x)=3x + 3

Answer 11
