Respuesta :

The function value of given function at x = 3 is 63.

Synthetic division :

The given function is,

                   [tex]f(x)=x^{3} +6x^{2} -2x-12[/tex]

We have to calculate function value when [tex]x=3[/tex].

              [tex]f(3)=3^{3} +6*3^{2}-2(3)-12\\ \\f(3)=27+54-6-12\\\\f(3)=81-18\\\\f(3)=63[/tex]

Thus, the function value of given function at x = 3 is 63.
