The vertex of the parabola is the center of the hyperbola x square / 16-y square / 9 = 1, the focus is the left vertex of the hyperbola, and the parabolic equation is?

The center line of the hyperbola is the origin
And the vertex is on the X axis
a²=16
a=4
So the left vertex is (- 4,0)
So open your mouth to the left
y²=-2px,p>0
Then the focus is (- P / 2,0)
So p / 2 = 4
2p=16
So y & sup2; = - 16x
