Question

Find the domain of
f(x)=(5x/6x-1)-(2x/5x-2)

Answer 1

is it {xlx >0}

Answer 2

is your equation 5x/(6x-1)-2x(5x-2)?

Answer 3

\[5x \div6x-1\]

Answer 4

and subtract that from \[2x \div5x-2\]

Answer 5

domain will be X/=0

Answer 6

X can be both positive and negative numbers

Answer 7

oh yea thats right

Answer 8

x not = 0 is correct

Answer 9

yea :)

Answer 10

help me with 1 more?

Answer 11

f(x)/g(x)

f(x)=x+1/x and g(x) = x+2/x+3

Answer 12

\[f(x)/g(x)=(x+1)(x+2)/(x)(x+3)\]

Answer 13

all you need to do is to make sure denominator doesn't go to 0, so domain will be: x/=0,-3

Answer 14

does x/=-1 and x/=-2 works too?

Answer 15

yea it will just go to zero if the numerator equals to 0

Answer 16

Thank you
