Question

What is f^1(3) when f(x)=(2x-7)/3 ?

Answer 1

* f^-1(3)

Answer 2

8

Answer 3

First you need to invert the function

Answer 4

I got 8 too, but I have a question that asks which statements have the same result, and I got 8 for all of them. So I dont know where I went wrong.

Answer 5

I\[y=( x/3 +7) / 2. \]

Answer 6

Is this what you got for the inverse? If so I came up with 4.

Answer 7

No, I put y=(3x+7)/2. Wouldnt you multiply both sides by 3?

Answer 8

Your right. My error

Answer 9

So you did get 8?
