1. Consider the function f(r, y) = e=y. (a) Graph the level curves for this function for k = e, e?,e3, and e4 on the same graph to make a "topographical map" of the surface. Make a conjecture based on this graph what the surface looks like, in words. (b) Find the first and second partial derivatives of f. (c) Find an equation of the tangent plane of f(x, y) at the point (In 2, 3, 8). Use this to approximate the value of f(x, y) at (In 2 + 0.01, 3.02).

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
