Question 968671

{{{f(x)= log(7,(5x+1))}}}

the domain of {{{f}}} will be all except {{{x}}} that makes {{{5x+1=0}}} and it is: {{{5x+1=0}}}=>{{{5x=-1}}}=>{{{x=-1/5}}}

or,  
{ {{{x}}} element {{{R}}} : {{{x>-1/5}}} }

 in interval notation:

({{{-1/5}}},{{{infinity}}})


{{{ graph( 600, 600, -10,10, -10, 10,log(7,(5x+1))) }}}
