Question 934452
if you have:
{{{f(x)=-sqrt(x)+1}}}

domain will be:

{ {{{x}}} element {{{R}}} : {{{x>=0}}} }  (all non-negative real numbers)

range:

{ {{{f(x)}}} element {{{R}}} : {{{f(x)<=1}}} }

{{{ graph( 600, 600, -10, 10, -10, 10, -(sqrt(x))+1) }}} 

but,if you have:

{{{f(x)=-sqrt(x+1)}}}

domain will be:

{ {{{x}}} element {{{R}}} : {{{x>=-1}}} }  (all non-negative real numbers)

{ {{{f(x)}}} element {{{R}}} : {{{f(x)<=0}}}}  (all non-positive real numbers)

{{{ graph( 600, 600, -10, 10, -10, 10, -(sqrt(x+1))) }}}
