In what direction and by how many units is the graph of f(x)=5cos(4x-pi)-1 vertically and horizontally shifted?
go down by 5 units and move left by pi.
@satellite73
i think i have answered @Patsfan12
I don't think you go down 5 units
down one on account of that \(-1\) out at the end
as for right or left, easiest thing to do is solve \[4x-\pi=0\] for \(x\)
you get \[x=\frac{\pi}{4}\]
so sorry go down by 1 unit and shift right with pi units sorry @Patsfan12
I see it now! Thanks guys!
hmm no
Wouldn't you go up 4?
compared to the graph of \(y=\sin(4x)\) the graph of \(y=\sin(4x-\pi)\) is shifted to the right \(\frac{\pi}{4}\) units
here look at the picture http://www.wolframalpha.com/input/?i=5sin%284x-pi%29-1
My answer choices are: up 4,right pi/4 Up 4, left pi/4 Down 4, left pi/4 Up 4, left pi/4
@ribhu @satellite73
?
Down 4, right pi/4?
correct.
Are you sure?
Was this correct?
