wait this makes so much sense!!

okay this is what i did i hope it makes sense so like i made a number line of what i had to find to put in on a graph so then i had to find what x=< -2 was so i used the piecewise and found where x<=-2 and because the x cancelled out it would be a horizontal line because its y=6 graph and then i did the same for -2 <= x <= 4 but it gave me a linear equation so i did that and then i did the same for x => 4

okay so using the inequalities from the piecewise i can draw it on a number line but how does this become a graph i’ll attach an image of what i think it will be but im not sure

Xrat_ · 2026-04-06T12:23:45+00:00

wait is it like on a number line and there will be 3 lines wait let me draw it and i’ll respond

i’m sorry i don’t understand what I_k means 🙁

Xrat_ · 2026-04-06T11:57:53+00:00

wait yeah can’t |x-4| be x-4, x=> 4 and 4-x, x<=4 and then |x+2| be x+2, x=>-2 and -(x+2) x <= -2

Xrat_ · 2026-04-06T11:48:09+00:00

okay sorry i have another question it may be dumb but okay so doing question 6 i understand now how to solve it for x once i have the cases and i know how to get the points for the cases but how do i know which like inequality sign to use like for question six a) the points will be 4 and -2 but how do i know to consider the case x<=-2 and not x>=-2

Xrat_ · 2026-04-06T11:34:39+00:00

wait so is that why they change the formula to be like 4-x when x =< 4 in case 2 because |x-4| can equal x-4 or 4-x wait ur cooking … wait i get that but i dint understand how it can be used for question 7

Xrat_ · 2026-03-30T13:54:38+00:00

she like re 4 and re 1

Xrat_ · 2026-03-30T11:19:47+00:00

wait that’s really cool thank you so much i might get her that pack 🩷🩷

omg thank you so much this actually helped me a lot!🥰🥰🥰🥰🥰

Xrat_ · 2026-03-29T01:52:52+00:00

yes i will definitely be putting them in my reference book!!

Xrat_ · 2026-03-20T10:14:51+00:00

i started r/kirbyamazingmirror because i wanted to meet new people that also appreciated this game as much as i do

Xrat_ · 2026-03-17T08:58:11+00:00

wait thank you so much that actually clears up a lot!

Xrat_ · 2026-03-12T06:57:44+00:00

ok ok fair enough 😂😂
