Best ResponseYou've already chosen the best response.1Can you figure out the directrix, remember how I said vertex is in the middle of directrix and focus, so your directrix will be?

Best ResponseYou've already chosen the best response.1\[y = \frac{ 1 }{ 4p }(xh)^2+k\] similar as previous question except now we have 7 as our p

Best ResponseYou've already chosen the best response.0y = 1/7x^2 y2 = 7x y =1/28x^2 y2 = 28x

Best ResponseYou've already chosen the best response.1Np, also notice the negative represents the vertical reflection, meaning the parabola will open down :), just a hint on the way to draw it if you get stuck :P
