@dan815 please help me with math

it is simple since I have to decrease the value of the y-coordinate by 2 units, so k=2
anonymous
  • anonymous
so it is K = 2 ?

\[\large\rm f(x-h)=\] horizontal shift \[\large\rm f(x)+k=\] vertical shift h units shift to the right or left ( if h is negative then some units to the right , if h is positive then some units to the left) k = vertical shift k tells us how many units we should shift the graph up or down if it's negative then k units down if it is positive then k units up

okay so it would be k = -2 right?
Nnesha
  • Nnesha
`down by 2 units `

negative sing is already in the equation \[\large\rm y=(0.5)^x\color{ReD}{ -} k\] i guess x is an exponent right

yess

so it would be a negative number right?

Nvr mind I saw what you said, it is already in the equation
Nnesha
  • Nnesha
hmm let's say it's -2 sub k for -2 \[\large\rm y=(0.5)^x\color{ReD}{ -} (-2)\] you should substitute -2 by -1 = `+2` by the question says `down 2 unit`
Nnesha
  • Nnesha
but* not by

  • anonymous
so it is 2 then right? @Nnesha
Michele_Laino
  • Michele_Laino
that's right!

\[\large\rm y=(0.5)^x\color{ReD}{ -} (+2)\] looks good to me 2
