Math 115H (Assignments)

# Homework on 15 September 2017:

1. [Not to be turned in] In class, we talked about how to use $x$- and $y$-traces to understand the graph of a function $f\colon\R^2\to\R$ and used the example $f(x,y) = x^2 + y^2$, whose graph is a paraboloid.

Apply similar techniques to the following functions, to see if you can get a sense of what they look like

1. $f(x,y) = x^2 - y^2$
2. $f(x,y) = x^3 - y^2$
3. $f(x,y) = xy$
2. Do the next WeBWorK assignment.
