Modulus as hybrid functions?

[crayolé]

Can someone please explain to me how this works?

I'm having a lot of trouble trying to grasp this concept ( turning a modulus function into a hybrid function)

i suggest u read this http://vcenotes.com/forum/index.php/topic,24739.0.html

Perhaps it would be more helpful if you posted up a question or two on it.

Alright,

What would be the steps you would take to write |2x+3| as a hybrid function?

[superflya]

take out the 2,   

split into 2 cases





theres ur hybrid.

Ok, this is my attempt at explaining it, (I'm stupid but, so let someone confirm ).

Take the modulus function

We know that the absolute value function only spits out magnitude, so only positive numbers, now this is where the hybrid comes in.

We know that when then . However when , then the terms in the modulus must be multiplied by a negative to make it into a positive, so .

So the hybrid function of this would be:



Then you solve for x in the domain, I usually do this before writing the hybrid function.



EDIT: Beaten...

Thanks Blak for the long explanation ;]
I think i get it now
