(a) $none$ (b) $none$. (c) $5$. (d) $y=3x^6$.

Work Step by Step

(a) Given $f(x)=3(x^2+8)^2(x^2+9)^2$, we can find zero(s) $none$ (multiplicity none). (b) The graph touches or crosses the x-axis at $none$. (c) The maximum number of turning points on the graph is $n-1=6-1=5$. (d) The end behavior is similar to those of $y=3x^6$.
