Determine the signs (positive, negative, or zero) of y=f(x)\displaystyle {y}={f{{\left({x}\right)}}} (shown in the graph) and f(x)\displaystyle {f}'{\left({x}\right)} and f(x)\displaystyle {f}{''}{\left({x}\right)} when x = 3.

The sign of f(3)\displaystyle {f{{\left({3}\right)}}} is
The sign of f(3)\displaystyle {f}'{\left({3}\right)} is
The sign of f(3)\displaystyle {f}{''}{\left({3}\right)} is
