Question

Helpppp pplease!!!!

Answer 1

The graph of f(x) = (0.5)x is replaced by the graph of g(x) = (0.5)x - k. If g(x) is obtained by shifting f(x) down by 2 units, the value of k is ________.

Answer 4

@dan815 please help me with math

Answer 5

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

Answer 6

so it is K = 2 ?

Answer 7

\[\large\rm f(x-h)=\] 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

Answer 8

okay so it would be k = -2 right?

Answer 9

`down by 2 units `

Answer 10

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

Answer 11

yess

Answer 12

so it would be a negative number right?

Answer 13

Nvr mind I saw what you said, it is already in the equation

Answer 14

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`

Answer 15

but* not by

Answer 16

so it is 2 then right? @Nnesha

Answer 17

that's right!

Answer 18

Thanks @Michele_Laino !!!

Answer 19

:)

Answer 20

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