Question

Which is a solution of the absolute value function y = |x - 4| +2.
A. (4, 2)<--- my answer

B. (2, 4)

C. (-4, 2)

D. (2, -4)

Answer 1

how? can you show how you solved it?

Answer 2

do u divide

Answer 3

I'm assuming you mean "the vertex of the expression" ?

Answer 4

yes

Answer 5

|x - 4| <--- what value for "x" makes that = 0?

Answer 6

|x-4|+2

Answer 7

yes.... but just focusing on the absolute value expression
what value of "x" would make the expression 0?

Answer 8

do you divide them and get 2

Answer 9

well...hmmm 2?

Answer 10

anyhow... well.. no you don't have to divide them....
you'd just get a value for "x" that makes the absolute expression =0 thus

|x - 4| <--- what value for "x" makes that = 0?

Answer 11

oh okay -4

Answer 12

so will it be c

Answer 13

0-4=-4

Answer 14

let's see x = -4 |(-4)-4| = | -8| = 8
well. no dice on -4

so what do you think it'd be?

Answer 15

well i think this is confusing lol

Answer 16

heehe

I didn't mean to say set x = 0
I meant to say
a value for "x" that makes the expression in the bars =0

so say for example | x -25|
if I set x = 25 then the expression becomes => | (25) - 25| => | 0| = 0
so x = 25 makes | x-25| to 0

Answer 17

25

Answer 18

for |x - 25| yes, that'd make it 0
how about for
| x - 4 | ?

Answer 19

would it be x=4

Answer 20

yes

Answer 21

\(\bf |{\color{red}{ 4}} - 4| +{\color{red}{ 2}}
\\ \quad \\
({\color{red}{ 4,2}})\Leftarrow vertex\)

Answer 22

so my answer was right it was a

Answer 23

well, yes, but now you know how to obtain the vertex

Answer 24

well thanks you amazing

Answer 25
