The parabola with with a vertex at (-4,-2) represents any member of parabolas with the equation where
is any real number with the exception that
.
The reason any equation of the form works is that there are an infinite number of parabolas with a vertex at (-4,-2). All of these parabolas are formed by applying some transformation that involves a vertical translation of -2 and a horizontal translation of -4 on the parabola
. The different variations are archived by varying the constant
. When
is negative, the parabolas will face downwards. When
is negative, the parabolas will be face downwards.
