What logarithmic function represents the data in the table? x f(x) 216 3 1296 4 7776 5

Nnesha (nnesha):

what logarithmic ? do you have choices ?

OpenStudy (vera_ewing):

f(x) = logx 5 f(x) = 6 log x f(x) = log 6x f(x) = log6 x

OpenStudy (amorfide):

you know it is a log function you know that the cube root of 216 is 3 so I would assume log base 6 of x

OpenStudy (vera_ewing):

So D is the answer?

OpenStudy (amorfide):

because

OpenStudy (amorfide):

\[\log_{a}(b)=C\] then \[a^{c}=b\]

OpenStudy (amorfide):

I am not going to give you the answer directly try it out do the function replace x with the number given do log base 6 of 1296 if it gives you 4 great! then do it for the next number

OpenStudy (vera_ewing):

f(x) = log6 x works so that's the answer?

OpenStudy (amorfide):

well done :)

OpenStudy (vera_ewing):

thanks
