Question

Write y = 2x as a logarithmic function.

Answer 1

Try taking the log (either common or natural log) of both sides of this equation, y = 2x.
what do you get? simplify as much as possible.

Answer 2

howwwwwwwwwwwwww

Answer 3

Have you relevant examples on hand? For example: If y=x, log y=log x; If y=2/x, then log y=log 2-log x. These examples follow basic rules of logs. Tell me what you've already learned about logs and what you've done with them so far.

Answer 4

nothing really i forgot everything about using log

Answer 5

Billy, I'd be glad to help. But I am not here to teach you things that you once knew, have forgotten and have not yet reviewed. I need your active involvement in this discussion. So do you, if you want to understand and remember this material.

Unfortunately, I need to get off the 'Net now, for a while at least. When you've looked up "rules of logs" and tried a few sample problems, come back onto OpenStudy and tag me, and we'll resume this conversation.
