Which statement is true for this log function?

[matthewicee]

I'm confused about which statements are true as I thought the domain and range were real numbers. I would greatly appreciate an answer and an explanation because I'm not sure which two answers are right.

Please look at the graph of say f(x) = log₁₀(x) and tell us what you think the domain and range is? In fact you should be able to decide whether each choice is correct or not simply by looking at a log graph where b>1.

what does the b stand for

what does the b stand for

The base. They gave you log_bx

Please post a graph of y = log_bx (you pick any value for b as long as b>1) and then try to answer the questions.
