Question 912458
{{{g(x) = 10^(x-3) }}}

{{{ graph( 600, 600, -5, 5, -3, 3, 10^(x-3),10^(x-3) ) }}} 


domain: {{{R}}}  (all real numbers)


range:{ {{{g}}} element {{{R}}} : {{{g>0}}} }  (all positive real numbers)
as you  can see, a graph of this function goes very close to {{{g(x)=0}}} but it is not equal to zero 



{{{g(x) = 15-5^x }}}


{{{ graph( 600, 600, -15, 15, -5, 20, 15-5^x,15-5^x ) }}} 


domain: {{{R}}}  (all real numbers)


range:{ {{{g}}} element {{{R}}} : {{{g<15}}} }
