Given:
There is a diagram given in the question
Required:
We need to find the equation of parabola and focus
Step-by-step explanation:
As we can see that vertex point of parabola is origin
the general equation of parabola is
now substitute the values
now by diagram there is a point
we use this point to find the a
Plug the point in equation
Now the equation of parbola is
now the coordinate of focus is
substitute all the values
Final answer:
Coordinate of focus is
