Answer 3

you need the answer ?

Answer 4

One question at a time.

If f(x) = 8 – 3|x + 2|, find f(–6)

All you have to do is plug -6 into the equation.

Answer 5

sorry I was afk but the first question would be... A?

Answer 6

no it would be D

Answer 7

that was my second guess, I always get mixed up with the negatice and positive number's when using "|" XD thank you

Answer 8

yw

Answer 9

can you help with me the second one?

Answer 10

what would the graph look like when its absolute?

Answer 11

A and C?

Answer 12

Im going with C

Answer 13

or thats what I think it is

Answer 14

no

Answer 15

ok um.. what would x be?

Answer 16

any thing actually

Answer 17

its an absolute

Answer 18

oh ok so any positive number that matches the graph?

Answer 19

yes

Answer 20

k :) um... were looking for a graph this is absolute right?

Answer 21

yes

Answer 22

the best graph that i see that fits all my numbers A

Answer 23

can you help me with one more?

Answer 24

sure

Answer 25

thanks =D

A.
f(x) = |x| + 2

B.
f(x) = |x| – 2

C.
f(x) = |x – 2|

D.
f(x) = |x + 2|tion.

Answer 27

Im thinking B but I could be wrong, ( I'm bad at using graphs)

Answer 28

hmm

Answer 29

wait I don't think that there should be a "tion" on answer D.

Answer 30

let me check

Answer 31

oops sorry :( dont know were that came from...

Answer 32

lol ok so did you try putting random numbers from the graph into the equations?

Answer 33

yes and no, I did but im confused

Answer 34

wait one thing that you should know.
if you have a equation like that f(x) = |x| + 2
your graph would look like

Answer 35

so A is out?

Answer 36

but if you have these kind of equations f(x) = |x – 2|
your graph would look like this

Answer 37

yes A is out
