Answer:
<em>d) The equation of the standard parabola</em>
<em> x² = 6 y</em>
Step-by-step explanation:
The given directrix is y= -31.5
The equation of the parabola is of the form x² =4 a y
Given focus (0,1.5) , Here a= 1.5
The equation of the standard parabola
x² = 4 a y
x² = 4 (1.5)y
x² = 6 y
<u><em>Conclusion</em></u>:-
<em>The equation of the standard parabola</em>
<em> x² = 6 y</em>
