OpenStudy (anonymous):

if the vertex is (-3,-25) you can write \[-25=(-3)^2+6\times (3)+c\] and solve for c

OpenStudy (anonymous):

or you could write \[0=(-8)^2+6\times (-8)+c\] and solve for c

OpenStudy (anonymous):

for that matter you can write \[y=(x+8)(x-2)\] multiply out and find c. that may be easiest. \[y=x^2+6x-16\]

OpenStudy (anonymous):

in fact the very very simplest way to do it is take the zeros, -8 and 2, and multiply them together to get \[c=-16\]
