Question

Help me solve this piecewise function pls.
f(x) = 0 if x <0
0 if x is greater than or equal to 0

g(x) = -x if x < 0
0, if x is greater than or equal to 0

f+g=?

Answer 1

What don't you understand?

Answer 2

im just not sure what to do. Thats why i just need an example of f+g so i can see it. It's like you add the first line of each right?

Answer 3

Try graphing it...Do you know how? I am not very good at explaining mathmatics without graph paper and not in person but you know who is excellent at it? @satellite73 @amistre64 @hartnn @Callisto ! There is a reason they are mods here!

Answer 4

Now, try not to have to fall back on the mods too much because they are very busy. Be patient, they will help when they get a chance.

Answer 5

I have a test in 2 hours though :(

Answer 6

@surjithayer can you help please?

Answer 7

Its okay, they will be here soon!

Answer 8

I literally just need this one answer so i can see how its done so i can do f-g, f*g, and f/g

Answer 9

Well, I will stick here with you to make sure you get some help. Give them some time I have contacted them.

Answer 10

ok

Answer 11

@SnuggieLad can you maybe help me with something eles than?

Answer 12

f(x) = 0 if x <0
0 if x is greater than or equal to 0
What does this function imply?

Answer 13

Whatever x you have, it is still....?

Answer 14

for f+g i got -x if x<0 and x if x is greater than or = to 0

Answer 15

Right. f has no effect when doing the addition as its value is always 0. So, f+g just depends on g.

Answer 16

oh, ok.

Answer 17

do you think u can help me with another problem?

Answer 18

it is really \(f(x)=0\) in both cases? or is there a typo there?

Answer 19

umm no? i don't know. All i know is i just based it off an answer i saw in the book so thats how i did it.

Answer 20

I am sorry that I have to go now. Best of luck for your test.
