From my experience, neither can count well.

Isn't there a "you used to be cool" part in there somewhere...?

3. ## Relations & Functions

Here is one of the most complicated things i've ever done in maths its so confusing

FH (X) = 2X - 3
X +4

Find A: H (-3)
B: H(1/2)
C: H(5)

D: Calculate the value for X if (1): H(X) = 3
(2): H(X) is undefined

4. A ---> x = -1.8
B ---> x = 5 and a third
C ---> x = -5 and two thirds
Da ---> x = -15
Db ---> x = (3 + 4H(X)) over (2 - H(X))

I thinks...

I thinks...
explain how you worked out the undefined part???

6. What you have do is thus get the X by itself...

I think it might be a paint job to show you :P

I'll post it in a second.

7. Here it is... nice use of arrows i think.

indeed. Very pretty

...Why do you multiply by -1, though?

9. Makes it cleaner later on...

It just makes it easier to only have 1 negative item instead of 3. Helps later on, i feel.

10. And the best bit is that you are allowed to do that kind of thing, to clean up maths when x and y are involved.

ahhhh i think i get it now.......

12. man this topic should be stickied.that functions thing helped me

13. I am not good at math either,

14. Hahah nice Bob. I've just done circle geometry, variation, quadratic graphs and exponentials.

FH (X) = 2X - 3
X +4

Find A: H (-3)
B: H(1/2)

LOL, transposing, can't believe you haven't done that

Reminds me of a mathematician's saying: God created the natural numbers, Man made the rest.
