Answer:
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}
1.98x10^9. move the decimal until you have one number in front of it. then keep the numbers that are not 0 after it. then count how many places you moved the decimal point and that's your power.
