this should help you out

Answer 2

that didn't help sadly

Answer 3

in words, where -x values correspond to the y of the positive x value

Answer 4

can you explain more please

Answer 5

y axis is reflected :D whoops

Answer 6

perfect immanuelv!!

Answer 7

hmm im still kinda lost

Answer 8

that was a much better was of saying it

Answer 9

way*

Answer 10

i know f(x)=1/2 is .5 on the y axis why does |x| spread the graph like that

Answer 11

so f(x)=.5x produces a line, this is beacuse for the -x values the y values also become neg. so when you have f(x)=.5Abs(x), where x = -2 for example, plug the value in. so .5Abs(-2)= .5(2)= 1, so your y=1 and you x = -2 graph it.

Answer 12

it looks like that because for the -x value it produces a positive y, instead of the expected -y. which would produce a line instead of a "v" shape

Answer 13

get it?

Answer 14

if you still don't understand ping me
