First off:  Would you know how to graph y=log x?  That's base 10.

alex6799 · Answer

not really

mathmale · Answer

The graphs of y=log x and y=(log to the base 5) of x have the same basic shape, but one of these functions grows faster than does the other.

mathmale · Answer

You could make a table of values and then plot some points and connec them with a curve.

alex6799 · Answer

so the correct answer is C?

mathmale · Answer

Please, alex, don't ask for "yes" or "no" responses.   If you believe that C is the correct answer, please justify it.  You need to know and understand the graphing of log functions.

mathmale · Answer

x         log x (log to the base of x)
----------------------------
1           log 1 = 0
10         log 10 = 1
100                     2
1000                    3
0.1          log 0.1 = -1

and so on.   Are you able to plot these points and to draw a rough graph of y = log x?

mathmale · Answer

By the way, C is not correct.

Why not look up "logarithmic function" on the 'Net and look for sample illustrations of such functions?

im gonna go with B..i dont have much time left on my exam :$

mathmale · Answer

Your choice.  I would so much prefer to discuss the mechanics of graphing log functions, so that you'd have solid backround in this topic.

Please come back later for more discussion, when you have time.
