1.15. consider the unit cube in the first octant (x; y; x 0) with the primary vertex at the origin as a test volume and the velocity field f(x; y; z) = 2 4 zx yx yz 3 5: if the source term r(x; y; z) is zero everywhere, determine if the mass inside the cube is growing or shrinking.

Which statement is true about the function f(x)= square root -x ? the domain of the graph is all real numbers. the range of the graph is all real numbers. the domain of the graph is all real numbers less than or equal to 0. the range of the graph is all real numbers less than or equal to 0.
