f(x) = |2x-1|, f(x) = 2

OpenStudy (anonymous):

|x| = n can be broken up into 2 equations x= -n and x = n

OpenStudy (anonymous):

ok, I thought that it was negative and positive. would the answer then be: (3, -5) ??

OpenStudy (anonymous):

|3*2 -1 | = 5 \[5\ne 2\]

OpenStudy (anonymous):

2(2) -1 = 3 & 2(-2) = -5 is what I thought when it is broken down into 2 equations?? how do you get 5 does not equal 2?

OpenStudy (anonymous):

f(x) =2 f(x) = |2x-1| im assuming the point is to solve for x

OpenStudy (anonymous):

substituting will give us 2 = |2x -1|

OpenStudy (anonymous):

the question is not asking for f(2) = ?

OpenStudy (anonymous):

the result of anything within an absolute value will always be positive

OpenStudy (anonymous):

oh, gotcha. thank you.
