graph 2/x then move it down 3

dumbsearch2 · Answer

How do you graph 2/x?

dumbsearch2 · Answer

I know how to graph it in this formula: y = a (1/(x-h)) + k...but what does the 2 do?

zzr0ck3r · Answer

i would look more at what the 2 does to 1/x
it multiplies everything by 2
so what was at 1 is now 2
what was at 2 is now 4
what was at 1/2 is now 1, so it "squeezes" 1/x

dumbsearch2 · Answer

Do you mean that I should multiply 2 by the y coordinates?

dumbsearch2 · Answer

For example, if I move the point from 1,1 down 3 units, then should I multiply the parent function y coordinate by 2?

zzr0ck3r · Answer

try it

dumbsearch2 · Answer

would this be right: 2,-2? But then, I multiplied the x coordinate...
