Question

f(x)= /x/ +10 ; f(-4)
is it linear or not linear?

Answer 1

Hello Kirito-kun

Answer 2

hello! do u think u can help meee? lol this is so hard for mee

Answer 3

F(-4)= |-4| + 10
= 4+10=14
I think it's not linear but not so sure

Answer 4

@phuongduongm modulus can open with +ve value or with -ve value

Answer 5

thanks guys for helping!! :D

Answer 6

@jellybean11122 here is your answer :-
\[\large \bf f(x)=\left| x \right|+10\]
Modulus can open with both +ve and -ve value.
So,there are 2 cases.
1 Case :-
when open with +ve value :-
\[\large \bf f(-4)=+(-4)+10=-4+10=6......(1)Answer\]
2 Case :-
when open with -ve value :-
\[\large \bf f(-4)=-(-4)+10=4+10=14....(2)Answer\]

So there are 2 possible answers.
And both answers have not any variable they all are constant.
So,they are NOT LINEARS.
