Question

consider the contour diagram for the function f(x, y)

Answer 1

sketch a graph of f(x,0)

Answer 2

parallel contour lines suggest a plane

Answer 3

part be ask whether \[f_{xx}(0,0) and f _{xy}(0,0)\] is positive, negative or zero

Answer 4

I think that \[fxx(0,0) \] is negative because it get bigger and bigger as you move f_x but i'm not sure

Answer 5

how would i sketch f(x,0) @ganeshie8

Answer 6

what are the units on x axis ?
