What is the domain of f(x)= 3x/ x-1

D : {x ∈ R : x≠1}

Step-by-step explanation:

The domain is what values of x can we put into the function and it still works

We cannot have the denominator equal zero

x-1 ≠0

Add 1 to each side

x-1+1 ≠0+1

x≠1

The domain is all real values of x except x=1

D : {x ∈ R : x≠1}

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
