Can someone help!? http://prntscr.com/dkh5p1

What do you think? What did you pick?

OpenStudy (lolipopss):

(1,0)?

jimthompson5910 (jim_thompson5910):

Step 1) Start at the vertex. Step 2) Measure how far it is from the vertex to the directrix (the dashed line). Call this distance D Step 3) Go back to the vertex and move D units in the opposite direction than in step 2. This will land you on the focus F

OpenStudy (lolipopss):

ok so it would be (0,1)

OpenStudy (3mar):

Why @lolipopss? You should know that the focus must be allocated on the y-axis as it is inside the parabola curve not outside it...

jimthompson5910 (jim_thompson5910):

yes that is correct @lolipopss
