Question 1126743
I guess {{{7}}} is the base

{{{f(x)=log(7,(49x))}}}

{{{f(x)=log(49x)/log(7)}}}

x-axis intercept:
{{{0=log(49x)/log(7)}}}

{{{log(49x)=0}}} .....since {{{log(10,1)=0}}} we have

{{{log(49x)=log(10,1)}}}=>

{{{49x=1}}}

{{{x=1/49}}}


{{{ graph( 600, 600, -5, 20, -5, 5, log(7,49x)) }}}


domain:
({{{0}}},{{{infinity}}})
.
range:
({{{-infinity}}},{{{infinity}}})

axis interception point:

({{{1/49}}},{{{0}}})

asymptotes: 

vertical: {{{x=0}}}

extreme points: {{{none}}}

{{{continuous}}}:does not  come apart at any point

{{{increasing}}} : in interval [{{{1/49}}},{{{0}}})
