Which word best describes the domain of a function?
input
output
dependent

"input"

Step-by-step explanation:

When talking about function, we always bring the terms "domain" and "range".

Simply put, the domain is the set of all values that we can put into the function and the range is set of all values that the function can give us (return).

So domain is the set of input given into the function and range is set of output that the function returns for those inputs.

Hence, domain are the input

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
