If there is such a scalar function <em>f</em>, then
Integrate both sides of the first equation with respect to <em>x</em> :
Differentiate both sides with respect to <em>y</em> :
Integrate both sides with respect to <em>y</em> :
Plug this into the equation above with <em>f</em> , then differentiate both sides with respect to <em>z</em> :
Integrate both sides with respect to <em>z</em> :
So we end up with
Answer:
The graph is possible for
Step-by-step explanation:
we know that
The discriminant of a quadratic equation of the form
is equal to
If D=0 the quadratic equation has only one real solution
If D>0 the quadratic equation has two real solutions
If D<0 the quadratic equation has no real solution (complex solutions)
In this problem , looking at the graph, the quadratic equation has two real solutions (the solutions are the x-intercepts)
so
therefore
The graph is possible for
