Find the value of x at which the function has a possible relative maximum or minimum point. (Recall that ex is positive for all x.) Use the second derivative to determine the nature of the function at these points. ftX)= (9+x)e'3" f'{x} = D f\"(x) = What is the value of x at which the function has a possible relative maximum or minimum point? x=D Is the point a relative maximum or minimum? tun minimum r.
