Answer 1

Answer:

x > 0

Step-by-step explanation:

I just got it right on 9.6.3

Answer 2

Answer:

C. $x>0$

Step-by-step explanation:

Given: $f(x)=log(8x)$

To find the domain of a logarithmic function, we need to take the argument, 8x, and set it greater to zero. This is because an argument of a logarithmic function cannot be zero or negative.

$8x>0$

$x>0$

So since x is greater than zero, we have just found out our domain:
