Question 926297


{{{y+20=8(x+7)^2}}} or {{{y=8(x+7)^2-20}}}

the quadratic is in vertex form {{{y=a(x-h)^2+k}}} where  {{{h=-7}}}, and {{{k=-20}}}

remember ({{{h}}},{{{k}}}) is the vertex 

{{{8(x + 7)^2 -20}}} gives us the vertex (turning point) of {{{y+20=8(x+7)^2}}}:

({{{-7}}},{{{-20}}})


{{{ graph(600, 600, -15,10, -30, 10,8(x+7)^2-20) }}}
