HI Guys,
I have been asked to sketch the function x^2+2y=4.

I'm not sure if I need to treat this as a Parametric curve and use a value of (t) for both functions to solve x = a cos (t) and y = b sin (t), or just solve for x and Y. ie say when x = 0 y = 2 and plot the and graph where x and y cut the Axis.

Any pushes in the right direction would be greatly appreciated
regards
Brendan
