Graph of paraboloid z=x^2+y^2
Graph of paraboloid z=x^2+y^2-The square root keeps us from going above that point z=4 if we manipulate the equation and isolate x 2 y 2 we get x 2 y 2 = 16 z 2 (remember that since we have a square root in our original function, we have to consider it's domain in our graph, meaning z <=4) This is the equation of a cone so we now know what we are looking atCurves in R2 Three descriptions (1) Graph of a function f R !R (That is y= f(x)) Such curves must pass the vertical line test Example When we talk about the \curve y= x2, we actually mean to say the graph of the function f(x) = x2That is, we mean the set
