How do I find the focus just from looking at a graph?
In the link below I have a screenshot of a parabola. I think the Focus is (4,0)
In addition to that, in the following graph, is the directrix of parabola? I think it is x = -5

By definition of parabola, the distances from any-point-on-the-parabola to the directrix and focus are equal :
Oh okay, so for the first one the correct answer would be (5,0)?

Am I right on the second one?
x = -5 is the equation of directrix line, yes
Write the equation of a parabola with a vertex at (0, 0) and a directrix y = -1.
What is the equation of the parabola with a focus at (0, -5) and directrix y = 5?
Write the equation of a parabola with a vertex at (5, 2) and a directrix y = 1.|dw:1435566317796:dw|
@ganeshie8 Am I right? I'm not sure what the medal means.
