You can put this solution on YOUR website!
h(x) = -3x^2
\n" ); document.write( "x^2 can never be negative since (-) x (-) = +
\n" ); document.write( "and (+) x (+) = +
\n" ); document.write( "so, -3x^2 can never be positive
\n" ); document.write( "this is the function h(x), so the range is 0 to minus infinity
\n" ); document.write( "any number can be put in place of x and h(x) will be a valid
\n" ); document.write( "number
\n" ); document.write( "So, the domain of x is minus infinity to plus infinity
