Question

Write the standard equation of the parabola.
Vertex (3,-5) and directrix x=2
Can anybody help me with this problem? I know how to solve when it is with focus instead of vertex.

Answer 1

they dont tell me that

Answer 2

i dont really get it;;;

Answer 3

is not it 3

Answer 4

@donghyun

Answer 5

3-2=1

Answer 6

Answer 7

i think u r not feeling comfortable @donghyun

Answer 8

i think ur focus will b S(4,-5)

Answer 9

did u get it

Answer 10

distance frm focus to vertex is also 1

Answer 11

so the equation of parabola will b\[(x-4)^{2}+(y-(-5))^{2}=(x-2)^{2}\]
