Question

For the function f(x)= log5 3x-10 explain why x=2 is not in the domain

Answer 1

Answer:

Step-by-step explanation:

The simple answer is that logs cannot be negative and if you insert a 2 where the x is located you get a negative. Logs have to be >= 0

It all has to do with logs being tied to exponents and exponents being tied to logs. Actually an inverse of an exponent is a log.
