Question

G(x)= 3x+mod of x/x .. sketch and find the domain

Answer 1

\[3x+\left| x \right|/x\]

Answer 2

Right so what do you think the first step should be since you did such a beautiful job on the previous question. Don't be afraid of being wrong. Trust me, I will be the first to let you know if you're wrong. LOL

Answer 3

sorry i am here now

Answer 4

i got stuck at the first step itself :/

Answer 5

Oh OK I just came back.

Answer 6

Is it\[G(x)=3x +\frac{ \left| x \right| }{ x }\]or is it\[G(x)=\frac{ 3x +\left| x \right| }{ x }\]The way you presented the question, I assumed it was the former but in your analysis you treated as the latter. Hence I need you to clarify as to which one is correct, before we proceed.

Answer 7

second one :)

Answer 8

OK! Please present questions clearly in the future. No worries though. Let's continue. Remember that

In other words, deal with the modulus function separately. For example, if given

2 - |x + 3| then first
Thus now

2 - |x + 3| = 2 - x - 3 = -1 - x if x ≥ -3

OR

2 - |x + 3| = 2 + x + 3 = 5 + x if x < -3

Do you see?
