Help!

zehanz · Answer

I think it is $$y=\frac{ 3 }{ 4x-12 }$$

zehanz · Answer

We can rewrite this one as:$$y=3 \cdot \frac{ 1 }{ 4(x-3) }=\frac{ 3 }{ 4 }\cdot \frac{1}{x-3}$$Do you know what the factor 3/4 does with a graph?

zehanz · Answer

It shrinks with respect to the x-axis. This means, if your original graph went through, say, (2, 10), the new grapg goes to (2, 7.5). Every point gets closer to the x-axis, the distance to it only 3/4 of what it was.
Hope you understand :)

zehanz · Answer

So you also understand that the graph has moved 3 units to the right!

To be honest, I do not understand the second part of the question either :(

zehanz · Answer

Hold on, lemme think about it...

zehanz · Answer

What about f(x)=1/(x²+1) ?
It is a rational expression, and x²+1 is always positive, so there is no chance of division by zero, so no vertical asymptote!

what about no hole

zehanz · Answer

@lala2: you're not the patient type, are you ;)

anonymous · Answer

sorry!just eager to understand

zehanz · Answer

No problem! 
THere is no hole, because the domain is all real numbers.

anonymous · Answer

oh ok.. that makes sense! thanks for all of your help!

zehanz · Answer

YW!
