Can i get help please dont understand this problem

Let f (x , y) = 32x^2 - 5y

Find the equations of the level curves for the heights z given below.

When z = 0,
the level curve is y = ........................

When z = 1,
the level curve is y = ......................

When z = 2,
the level curve is y = ...................

thank you

f(x,y) is the same as z. So just put in each value for z and solve for y:
0 = 32x^2 - 5y
y = 32x^2/5

1 = 32x^2 - 5y
y = (32x^2 - 1)/5

2 = 32x^2 - 5y
y = (32x^2 - 2)/5

You have to put something in for x and solve for y and then put something in for y and solve for x. I haven't done this in years though so I don't really remember, sorry
