Write the equation of a quadratic function that is concave down and has a vertex at the point (4, -2). The parabola is not stretched at all.\r
\n" ); document.write( "\n" ); document.write( "(Don't I need another point?? - He didn't give us one)
\n" ); document.write( "

Vertex form of the equation of a parabola: 
\n" );
document.write( "Since the parabola was NOT STRETCHED, and is concave down, then 
\n" );
document.write( "With vertex being (4, - 2), and a being - 1,  becomes: 
\n" );
document.write( "__________ \n" );
document.write( "

\n" );
