anonymous · Answer

$f(3)=|(3)-5|+2$

anonymous · Answer

4

anonymous · Answer

So does that make it 4?

anonymous · Answer

So once you plug it in solve within the absolute value sign and remember it is always positive. At the end, add 2 to your answer.

anonymous · Answer

$f(3)=|3-5|+2=|-2|+2=2+2=4$

anonymous · Answer

ok that helps a bit but I'm still not confident with the whole process.

anonymous · Answer

3-5=-2 , but the absolute value signs make it 2, then add the ending, 2+2=4

anonymous · Answer

Could you maybe help me on another?

anonymous · Answer

Of course (:

absolute value is just distance.  i live in san diego and tia juana is 30 miles south and la is 100 miles north.  they are in opposite directions but i don't say tj is -30 miles and la is +100.  they're 30 and 100, resp., but in different directions.

that's absolute value.  it's just the distance, not the direction.
