Question 1150039


given:

{{{f(x)= C * a^x}}}

if so, thean factor {{{3}}} => {{{a=3}}}

and if {{{f(5)=13}}} we have

{{{13= C * 3^5}}}

{{{C=13/3^5}}}


then

{{{ f(x)= (13/3^5) * 3^x}}}

and 

{{{f(6)=(13/3^5) * 3^6}}}.....simplify

{{{f(6)=(13/cross(3^5)) * 3^cross(6)}}}

{{{f(6)=13*3}}}

{{{f(6)=39}}}
