Question

Complete the equation for the inverse of f(x)
F(x)= (3x-2)/6
F^-1(y)=????

Answer 1

Put f(x)=y

Then solve for x.

Answer 2

I don't understand...

Answer 3

Switch x and y and solve for y.

Answer 4

f(x) = (3x-2)/6
f(x) = y
y = (3x-2)/6

now switch x and y and solve for y to find the inverse ^^

Answer 5

I feel so stupid for not understanding..... It's just going against what the lesson told me.... I think that's all.

Answer 6

The lesson basically says to just switch everything .... /:

Answer 7

It's okay..You can learn something new here :)

Answer 8

y = (3x-2)/6

x=?

Answer 9

I have no idea... Because how would I know if I didn't know what y was?

Answer 10

f(x) is another way to write y, it's just a different notation ^^

Answer 11

Okay.... So how would I know what x is? Ugh I'm so confused /: I'm sorry to both of you. This is all new to me.

Answer 12

Okay I have a better method if u find this confusing.

Answer 13

Wait it's asking for f^-1(y)???

Answer 14

Yes it is.

Answer 15

y = (3x-2)/6

x=?

Answer 16

I'm trying to find f^-1(y) the inverse to f(x)...

Answer 17

yes so answer my qn. x=?

Answer 18

It doesn't tell me...

Answer 19

Find x!!!

Answer 20

Hahaha, re-arrange the equation you have for x--so try to rearrange and leave x on one side using your algebra skills ^^

Answer 21

I don't know how to do this.... I feel so freaking stupid lol. It's because of the division /:
