vertex is where x=-b/2a so -2/1 or x=-2. That is also the equation of symmetry.
\n" ); document.write( "one coordinate is when x=0, y=1 (0, 1)
\n" ); document.write( "another is when x=1, y=3.5 (1, 3.5)
\n" ); document.write( "vertex is y=-1 when x=-2 (-2, -1)
\n" ); document.write( " $\"graph%28300%2C300%2C-5%2C5%2C-10%2C10%2C%281%2F2%29x%5E2%2B2x%2B1%29\"$
\n" ); document.write( "-
\n" ); document.write( "vertex is where x=-18/-6 or 3; axis of symmetry is x= 3
\n" ); document.write( "and y=2 so (3, 2)
\n" ); document.write( "x=0 y=-25 os (0. -25)
\n" ); document.write( "x=1 y=-10 so (1, -10)
