For ONE of the following, sketch level curves (a.k.a., contour lines) for f(x, y). (Be sure to label the height/z-value next to each curve.) Sketch (and explain the shape of) this surface. Explain how this would change if the equation were multiplied by -1. a. f(x, y) = (x² + y²)¹/2 b. f(x, y) = 2x²-y²
