Question

If f(x) = |x – 5| + 2, find f(3).
@gigi.antonia

Answer 1

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

Answer 2

4

Answer 3

So does that make it 4?

Answer 4

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.

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

Could you maybe help me on another?

Answer 9

Of course (:

Answer 10

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.
