Question

can anyone help with absolute value

Answer 1

let f(x)=│x-1│which of the following conditions holds true
A.f(x)=-(x-1) if x <1
B.f(x)=x-1 if x >1
C.f(x)=x-1 if x >0
D.f(x)<0 if x=0

Answer 2

will fan and medal

Answer 3

if \(x<1\) then \(x-1<0\) so \(|x-1|=-(x-1)=-x+1\)

Answer 4

so A is correct
there may be other correct ones too
if \(x>1\) then \(x-1>0\) so \(|x-1|=x-1\)

Answer 5

ok

Answer 6

can u help me with a few more

Answer 7

D.-8,3

Answer 8

\((-3,3)\)

Answer 9

can u help with this one

Answer 10

k

Answer 11

let f(x)={2x x<0
0 x>0
Which of the following is a equivalent definition of f(x)
A.f(x)=x+│x│
B.f(x)=2│x│
C.f(x)=│x│-x
D.f(x)=2x

Answer 12

i don't see a good answer from your choices
if say \(x=-2\) then \(f(-2)=-4\)

Answer 13

i can't figure out how to get \(-4\) from any of your choices except the last one
but the last one would not work if \(x>0\) so i am stuck

Answer 14

the 2x x<0 part at the top the 2nd x is supposed to have a little line under it
