2: the vertex and another point
Explanation:
the vertex gives the values
another point gives
these can be plugged into vertex form,
to get the equation of a parabola in standard form:
once the four values are plugged into vertex form, the equation can be solved for the variable
to find
finally, plug the
there are probably other ways to do this, but overall, a minimum of 2 points is needed
