Question 473017

hehe is a graph without limitation for {{{x}}} values:

{{{ graph( 500, 500, -10, 10, -10, 10,  -x^2) }}}

for {{{-1<x<=1}}} take only the part of previous graph from {{{-1}}} to {{{1}}}...make sure {{{-1}}} is excluded because {{{-1<x}}}


{{{ graph( 200, 200, -1, 1, -2, 1,  -x^2) }}}
