Homework Statement
Two separate problems:
1. Sketch f(x,y)=x+(y^2)
2. Sketch f(x,y)=sq rt (4-(x^2)-(y^2))
Homework Equations
The Attempt at a Solution
I honestly don't even know where to begin with sketching these two equations. In the first problem I can't find an example without a real number in the equation (all examples are similar to z=9-x^2-y^2) so I'm not sure how to begin. In the second example I realize the numbers in the sq rt need to be >=0, but I'm still not sure how to proceed and the most examples only show domain sketching. Any help would be greatly appreciated!
