Vertical stretching / shrinking
if i shrink 2x+6 by a factor of 1/2
that becomes x+3 correct?
as well if i stretch that by factor of 2
it becomes
3x+12?

am i understanding vertical stretches and shrinking correctly?

To shrink in half means to multiply by 1/2,
$\large\rm \frac12(2x+6)$ distributing 1/2 to each term, $\large\rm x+3$
So yes you're right on that account :)

How bout the stretch?
$\large\rm 2(2x+6)$
Hmm I don't think we get 3x, do we?

@zepdrix, understood, 4x+12, sorry

 for horiztional, we multiply the X only correct?
so it becomes x+6
