Question

Interval notation of this problem:

Find the domain of the function:
b) g(x)= 1/(x^2-x)

I know that x can't equal to 1 or 0, but I can't figure out how write the notation.

Answer 1

Do you know how to find the domain?

Answer 2

Yup! You set the bottom part of the fraction equal to zero right?

Answer 3

Ok so what is the domain?

Answer 4

In "Interval Notation" we just write the beginning and ending numbers of the interval, and use:

[ ] a square bracket when we want to include the end value, or
( ) a round bracket when we don't

Answer 5

Interval notation has to do with graphing can you graph this?

Answer 6

So can you find the interval notation of this one?

Answer 7

Which side is open?

Answer 8

hmmm... it would equal x<0 or x>10 or 0<x<10 but I'm not sure how to write the notation

Answer 9

Ok so if the side with the zero is open it is represented with a ( right?

Answer 10

oh the zero would be open and the 10 is closed

Answer 11

And if the side with the ten is closed than it would be represented with a ] right?

Answer 12

Well you tell me which one is it?

Answer 13

(0,10]

Answer 14

Yes the zero is open and the ten is closed so what is the notation

Answer 15

Correct!!

Answer 16

Ok so do you know how to graph your question?

Answer 17

yup I think i got it but just in case, I'll send you a picture of how i graphed it later to make sure I did it right

Answer 18

Ok

Answer 19

So did you get a solution?
