{{{y = x^2}}}-> the direction of opening: opens {{{up}}}, step pattern is ({{{1}}},{{{3}}},{{{5}}})

{{{y = 2(x - 1)^2}}}->the direction of opening: opens {{{up}}},  the vertex is ({{{1}}},{{{0}}}),  step pattern is {{{2}}}({{{1}}},{{{3}}},{{{5}}}) =({{{2}}},{{{6}}},{{{10}}}) 

{{{y = 2(x -1)^2+3}}}->the direction of opening: opens{{{ up}}},  the vertex is ({{{1}}},{{{0}}}),  step pattern is {{{2}}}({{{1}}},{{{3}}},{{{5}}}) =({{{2}}},{{{6}}},{{{10}}}) 


{{{y = -2(x-3)^2-1}}}->the direction of opening: opens {{{down}}},  the vertex is ({{{3}}},{{{-1}}}),  step pattern is {{{-2}}}({{{1}}},{{{3}}},{{{5}}}) =({{{-2}}},{{{-6}}},{{{-10}}}) 

{{{y =(x + 1)^2}}}->the direction of opening: opens {{{up}}},  the vertex is ({{{-1}}},{{{0}}}),  step pattern is {{{1}}}({{{1}}},{{{3}}},{{{5}}}) =({{{1}}},{{{3}}},{{{5}}})

{{{y =(x + 3)^2- 1}}}-> the direction of opening: opens {{{up}}}, the vertex is ({{{-3}}},{{{-1}}}),  step pattern is {{{1}}}({{{1}}},{{{3}}},{{{5}}}) =({{{1}}},{{{3}}},{{{5}}})
