Best ResponseYou've already chosen the best response.1It's not the x line that is moving up and down, but rather y moving?

Best ResponseYou've already chosen the best response.1the general form of equation of parabola that opens to right is \[\large x = \frac{1}{4c}y^2\] where \(c = \) distance between directrix and vertex

Best ResponseYou've already chosen the best response.1so the equation would be \[\large x = \frac{1}{4*\frac{1}{3}}y^2\] simplify

Best ResponseYou've already chosen the best response.1Yep :) thank you so much!! I had been accidentally writing it like dw:1433218892849:dw so that's why it was all wack
