ANSWER
EXPLANATION
The given parabola has directrix x=2.
This implies that, the parabola is opens in the direction of the negative x-axis because it must open in a negative direction to the directrix.
The equation of such parabola is of the form:
where (h,k)=(-5,8) is the vertex.
But the parabola opens to the left.
p=-7
The equation now becomes
