Question
Find the standard equation of a parabola that has a vertical axis and satisfies the given conditions.Vertex $(0,7),$ passing through $(2,-1)$
Step 1
In this case, the vertex is given as $(0,7)$, so we can substitute $h=0$ and $k=7$ into the equation to get $y=a(x-0)^2+7$, which simplifies to $y=ax^2+7$. Show more…
