The slope field for a differential equation is shown in the figure. Determine the general solution of this equation
answer choices y=Cx^2 x=Cy^2 x^2 – y^2 = C^2 x2 + y2 = C^2
okay so i know i have to reverse engineer this but i'm not doing too well
|dw:1439493039926:dw|
so i should just isolate the variables of each of the answer choices and derive each side right and graph all the diff equations i get and match it to the one im given , is that right?
Could you not let x = 1 and y = 1 and then set it up as dy/dx that way you can see the slope easier?
To my knowledge that slope field corresponds to a differential equation : \[y'=2x\] the family of solutions must look something like \[y = x^2+C\]

and yes you are correct @ganeshie8 i just cant get the differential equation when onlly given the solution to a differential equation
okay can you walk me through your answer ?
Wait, I don't know if it's right, but what I was thinking is as I said above, let x = 1, y = 1 or what ever and just let dy/dx = x/y^2 and then plug in the values and just observe the points...not sure if that's a good method haha, ganeshie definitely knows more.
the solution curves are the smooth curves obtained by joining the slope segments in the slope field : |dw:1439494028215:dw|
