Question

What is the domain of a function? I need to put this in my paper and am not sure what to write

Answer 1

if it is a function of x -> f(x):

the domain is the x values for which this function exists/returns a value

Answer 2

I know the definition but am not sure what else to say?

Answer 3

All the values of x that do not make the function undefined, i.e division by 0, negatives under an even root, numbers 0>= , etc o.o

Answer 4

*numbers 0 >= inside of a logarithm.

Answer 5

wtf...... o0

Answer 6

Er x_x values of x that don't make the function undefined.

Answer 7

er?

There's lots of practice at the bottom. It has range there, too... but you could ignore those questions.

Answer 9

Nvm, lol, I tried @_@

Answer 10

Domain
- is a set of input of the function.
- list of x-values

Poor Psymon :3

Answer 12

I already know that!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 13

@Psymon Thank you kind sir

Answer 14

Yes, poor, give me goldz x_x

Answer 15

these are values of 'x' which we put in the given function, which gives some output which is defined.

for example:- given function is f(x)=1/x , then the domain is all real values except 0 because it is not defined when the value of x is 0.

Answer 16

what exactly do you want to know??

Answer 17

What else I can write in my paper besides the defe.

Answer 18

@mary.rojas what about examples ?

Answer 19

maybe you can write, domains of different functions... like polynomials, rational, trigonometric & etc...

Answer 20

smh maybe I should stop doing things at the last minute so I can think straight.
THANK YOU BEAUTIFUL PEOPLEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
