you get
\[f(x+1)=|x+1|+4\]

OpenStudy (amistre64):
x-5 is not it

OpenStudy (anonymous):
that is replace x by x + 1

OpenStudy (amistre64):
you mighta typoed it tho, x+5 is good

OpenStudy (anonymous):
\[f(\spadesuit)=|\spadesuit|+4\]

god but i love that!

OpenStudy (anonymous):
can you explain why it is x + 5? because if you subtract 1 from the absolute value you should get x + 3...

OpenStudy (anonymous):
\[f(\heartsuit + \diamondsuit)=|\heartsuit + \diamondsuit|+1\]

OpenStudy (anonymous):

OpenStudy (anonymous):

replace x by x + 1. that is it

OpenStudy (anonymous):
you cannot simplify more?

OpenStudy (anonymous):
you get
\[|x+1|+4\] which is not
\[x+5\]

OpenStudy (anonymous):
nope

OpenStudy (anonymous):

f(x+1) = |x+1| + 4 = |x| +|1|+4 = |x| + 5

OpenStudy (amistre64):
-(x+1)+4 and (x+1)+4 maybe

OpenStudy (amistre64):
i dont think you can seperate a unary function like that

OpenStudy (anonymous):
yeah, ur right

OpenStudy (amistre64):
what does the title of the window say when you in here?
