Question

The domain of the function f(x)=8x / 5x−1

Answer 1

pls put in interval notation

Answer 2

u cant have denominator = 0, so 5x-1 not= 0. that gives us x not= 1/5
domain = (-infinity, 1/5)u(1/5,infinity) or
domain = (-infinity,infinity)-{1/5}

Answer 3

hey thanks for the help. can you help me with this also
The domain of the function f(x)=−15x+12 / x^2−7x+10

Answer 4

factor out the denominator u get (x-5)(x-2)
denominator not= 0
so x not=5 and x not=2
if u put into the notation form x = (-infinity,infinity)-{2,5}
or
x= (-infinty,2) u (2,5) u (5,infinity)

Answer 5

thanks for the help
do you mind, i have more questions?
