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 ________. Numerical Answers Expected! Answer for Blank 1:

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

6. anonymous

so it is K = 2 ?

7. Nnesha

$\large\rm f(x-h)=$ 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

8. anonymous

okay so it would be k = -2 right?

9. Nnesha

down by 2 units

10. Nnesha

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

11. anonymous

yess

12. anonymous

so it would be a negative number right?

13. anonymous

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

14. 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

15. Nnesha

but* not by

16. anonymous

so it is 2 then right? @Nnesha

17. Michele_Laino

that's right!

Thanks @Michele_Laino !!!

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