Answer to Problem 10E

The given parabolas focus is (0,p)=(0,12) and directrix y =12 .

Explanation of Solution

Given:

  x2=2y

Calculation:

The given parabolas focus and directrix is calculated below

  x2=2y

We find the value of p in the standard equation

  x2=4py4p=2p=12

focus : (0,p)=(0,12)

directrix : y=p or y =12

Conclusion:

Therefore, the given parabolas focus is (0,p)=(0,12) and directrix y =12 .
