According to the vertex and the directrix of the given parabola, the equation is:

<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:

In which a is the leading coefficient.
The directrix is at y = k + 4a.
In this problem, the vertex is (1,4), hence:

The directrix is at y = 7, hence:


Hence, the equation is:

Answer:
C
Step-by-step explanation:
No, she didn’t use the entire fraction as the base, so wrote the expanded form wrongly.
and I know this cuz I took the test
