1. 10.4 Translation of Conics
Matthew 7:21-23 "“Not everyone who says to me, ‘Lord,
Lord,’ will enter the kingdom of heaven, but the one who
does the will of my Father who is in heaven. On that day
many will say to me, ‘Lord, Lord, did we not prophesy in
your name, and cast out demons in your name, and do many
mighty works in your name?’ And then will I declare to
them, ‘I never knew you; depart from me, you workers of
lawlessness.’"

Parabola: ( x − h ) 2
= 4 p( y − k)
center is at ( h, k ) rather than the origin
so everything is shifted ...
horizontally h units
vertically k units
