Question

How do you find the Domain and range

Answer 1

of??

Answer 2

\[\frac{ x^{2} + x -2 }{ x^{2} -3x -4 }\]

Answer 3

Do you know what domains and ranges are??

Answer 4

No I don't know

Answer 5

the domain is the x value and the range is the y value

Answer 6

What exactly do you mean by the value

Answer 7

so in the coordinate pair (2,3) the domain in 2 and the range is 3

Answer 8

Oh okay, how do i find it?

Answer 9

do you have a problem/question you need to solve?

Answer 10

Yes, the one I gave above

Answer 11

ok the one that you are dividing the polynomials

Answer 12

Yes

Answer 13

ok what is \[x^2/x^2\]

Answer 14

1

Answer 15

yes now what is x/-3x

Answer 16

do you know

Answer 17

not exactly, i don't remember how i would even solve that

Answer 18

ok what you have to do is divide \[x/-3x\] and you will have to cancel out the x's to get 1/3 for that part

Answer 19

so that will be \[\frac{ 1 }{ 3 }\] and will i do the same for\[\frac{ -2 }{ 4}\]

Answer 20

yes exactly

Answer 21

So i would end up with this \[1 +\frac{ 1 }{ 3 } -\frac{ 1 }{ 2 }\] correct?

Answer 22

yes thats correct

Answer 23

What would I do after this?

Answer 24

simplify and answer

Answer 25

Okay I know this is way back but how would I simplify fractions

Answer 26

if u dont mind what grade r u in

Answer 27

11

Answer 28

ok how you simplify fractions is you have to find the GCFf of the denominator

Answer 29

i mean LCM AND THEN MAKE A PROPORTION

Answer 30

Im sorry for going back to simplifying fractions. The LCM is 6 and if i remember it right don't I multiple the numerator and then add the two equations?

Answer 31

yes u r correct

Answer 32

Okay and I'll end up with \[1\frac{ 5 }{ 6 }\]
