Say the vertex of a parabola is (-3,-2) What would be its equation

OpenStudy (kira_yamato):

\[y=(x+3)^2 -2\]

OpenStudy (anonymous):

I forgot to mention its vertice is not at the origin.

OpenStudy (kira_yamato):

Yes, it's not and that is the eq'n...

OpenStudy (amistre64):

if its vertex is at -3,-3; then it would evidently not be at 0,0

OpenStudy (amistre64):

and the equation would be: y = M(x+3)^2 -2

OpenStudy (amistre64):

where M is any multiple scalar

OpenStudy (amistre64):

except maybe 0 :)
