Question

Graph the function

f(x,y)=-x^2-y^2

Answer 1

? i understand that if you look at it from each axis point you can see that from the x it's going to look like a downwards parabola and same for the y but is there any other way of doing this

Answer 2

nah you have to pretty much have to plug in a bunch of values for x and see what the cross sections look like each time then after a bunch for y and see what those cross sections look like then imagine it... it pretty much looks like a pringle

Answer 3

nah it's a paraboloid

Answer 4

i have the picture just don't really know how to go systematically in doing it
