To find the product between those functions evaluated at x = 3, we can just evaluate each one at x = 3 and multiply the results. Evaluating those functions at x = 3, we have:
[tex]\begin{gathered} f(x)=x^2+4\Rightarrow f(3)=(3)^2+4=9+4=13 \\ g(x)=-x+2\Rightarrow g(3)=-(3)+2=-3+2=-1 \end{gathered}[/tex]
Multiplying the results, we have
[tex]f(3)\cdot g(3)=(13)\cdot(-1)=-13[/tex]
