Question 943451
Standard Form equation for a parabola, {{{y=a(x-h)^2+k}}}, the vertex (h,k) and vertical symmetry axis at x=h.  The given point included on the parabola can be used for finding the value for the coefficient, a.


{{{a(x-h)^2=y-k}}}
{{{a=(y-k)/(x-h)^2}}}
{{{a=(3-1)/(3-2)^2}}}
{{{a=2/1^2}}}
{{{a=2}}}


Equation:  {{{highlight(y=2(x-2)^2+1)}}}
