Absolute Value Functions

<< < (2/3) > >>

melanie.dee:
yep. and make sure if there is a domain defined you draw the endpoints on the abs graph too.

Eriny:

--- Quote from: "Timtasticle" ---Oww I see. Thanks!

This is probably a stupid question...But how about when you have like y= 5+ |x^2-1|

Oh how I wish I had have actually done some work in methods...

You do the absolute value part (as already explained) and then move it up five places. So, your range, instad of being [0, infinity) becomes [5, infinity)

asa.hoshi:
what about absolute functions that are like this:
y= |x+1| - |x+2|

bilgia:
addition of ordinates?

asa.hoshi:
and one more thing. i was reading the assessment report last year about the absolute function question they had.

you know when u reflect everything on the x-axis right, remember to place a "open" circle on the cusp if they have any. apparently students lost a mark because of that. the question was worth 2 marks.
