X =(y+2)^2
\n" ); document.write( "Solve and state the domain and range, and write in interval notation. Is this equation a function?
\n" ); document.write( "This is a parabola that opens rightwards with the vertex at (0,0)
\n" ); document.write( "Its standard form of equation: (y-k)^2=4p(x-h)X
\n" ); document.write( "(y+2)^2=x
\n" ); document.write( "This is a sqrt function where the radican x≥0
\n" ); document.write( "domain: [0,∞)
\n" ); document.write( "range: (-∞,∞)
\n" ); document.write( "equation is not a function.
\n" ); document.write( "To be a function, for each x-value, there can be only one y-value, and given equation has 2 different y-values for each x. \n" ); document.write( "

\n" );
