so do you know what the graph of 

$$y = \log_{5}(x)$$

looks likes...?

anonymous · Answer

which graph is the answer

campbell_st · Answer

ok... so start with a basic... 

do you know the equation of the inverse...?

anonymous · Answer

nop

campbell_st · Answer

ok... if I wrote 

$$x = \log_{5} (y)$$

can you make y the subject...? which will give the inverse...

anonymous · Answer

so x^5=y

campbell_st · Answer

not quite

y = 5^x... 

so if you use a table of values  

x = -2      -1    0    1     2
------------------------
y = 0.04  0.2    1    5     25

do you have a graph that appears to go though these points...?

if you do... the graph of 

$$y = \log_{5}(x)$$

is reflected in the line y = x....

anonymous · Answer

did u see the choices that I post

campbell_st · Answer

so perhaps a really easy solution is to draw y = x on the 4 graphs... and see which has an original and reflection... that don't intersect..

campbell_st · Answer

yep... I saw them... trying to help you understand them

anonymous · Answer

yeah thnx

campbell_st · Answer

so a positive exponential graph looks like 

|dw:1368914800298:dw|

maybe this helps
