a) $(-\infty,-3)\cup(1,\infty)$ b) $[-3,1]$
a) The equation: $g(x)=f(x)$ has the solutions $x=-3$ and $x=1$. The solution of the inequality $f(x)\lt g(x)$ contains all the values of $x$ for which the graph of $f$ is below the graph of $g$: $(-\infty,-3)\cup(1,\infty)$ b) The solution of the inequality $f(x)\geq g(x)$ contains all the values of $x$ for which the graph of $f$ is above the graph of $g$ including the intersections: $[-3,1]$
