If
you want to express the vertex form of an equation you have to know
that the vertex form of a parabola’s equation can be expressed as:
y = a(x - h)</span>²<span> + k. The way you know how the parabola will look like
is:
If
a is positive then the parabola opens upwards like a U.
If
a is a negative number, then the graph will open downwards like an
upside down U.
