Question 906509
{{{y=a(x-h)^2+k}}}----general model for standard form parabola equation.
You have AS GIVEN (h,k)=(8,-35).
Use your known specific point (10,-23) to find the coefficient, "a".


{{{y-k=a(x-h)^2}}}
{{{highlight_green((y-k)/(x-h)^2=a)}}}
{{{a=(-23-(-35))/(10-8)^2}}}
{{{a=(35-23)/4}}}
{{{a=12/4}}}
{{{highlight_green(a=3)}}}


{{{highlight(highlight(y=3(x-8)^2-35))}}}
