I know that it is missing terms. And it is a parabola facing left? What I do not know how to do is the rest. Since it is missing so many terms I am used to. Please help.

Determine the graph identity `y^2+8x=0` for `phi=6/pi` and write an equation of the rotated or translated graph in general equation form.

@EW: You are right that you are starting with a parabola facing left. In fact, here it is:

(I had to draw it in 2 halves because we are not dealing with a function, rather, it is a relation.)

The question is not as clear as it could be, but I presume it's asking us to rotate the parabola by the amount `phi`. I suspect the original question had `phi=pi/6`, right (not `6/pi`)?

I think the last solution offered there is the simplest to follow.

What method does your course use?

(BTW, my system spat the dummy when you were trying to submit this question because of the symbols used. I suspect you copied it from MS Word, or somewhere, right? I encourage you to use the math entry system in this Forum - it's easy and doesn't give errors.)
