Essays? But that's so boring -_-

Tell me about it -_- Thankfully there were only 3, this is my last one.

Sounds good

To get the inverse of a function
Like
f(x) = 4x - 16
for instance

If it wasn't an inverse problem I could do it but I don't understand how to solve inverse problems.

I have no idea, probably though. Good point, okay.

Got it?

Yes. And then you do it again but with x so it's x = 4y - 16, right?

lol
Then you add 16 to both sides?

So it should look like... |dw:1441987136393:dw|

@texaschic101
Can you help me please? The person who was helping me is having internet problems ._.

I have a name, you know :P

Well I don't know it :P

It's Kurt haha
Anyway, you did it correctly, just one more final touch ^^

You replaced f(x) with y.
Now we replace y.
With...
\[\Large f^{-1}(x) = \frac{x+16}{4}\]

Hey... Are you still there?

Just do the same, and use Pedro's bloody function :D

Okay so... f(x) =4x - 3/2
y = 4x - 3 / 2
x = 4y - 3 / 2
then add 3 to each side?

So we would cancel out the 2 all together?

\[\Large \color{red}2\cdot x = \frac{4y-3}2\cdot \color{blue}2\]

I'm lost .-. It's harder when it's already in a fraction.

OH OH, I got it now!! So... |dw:1441989280403:dw|

Yay! Thank you so much. You are a life saver... well grade saver I guess ^.^

No problem. ^_^
I am like super smart, after all...
AHAHAHAHA
or maybe just a little :)

Or a lot :P
