Answer:
[tex]f(-6)=14[/tex]
Step-by-step explanation:
The remainder theorem tells us that If a polynomial f(x) is divided by a linear factor, L(x)=x-a, the remainder of the quotient is f(a).
In this case:
f(x) divided by x+6 has a remainder of 14.
Comparing the linear factor with x-a, we have:
[tex]x+6=x-(-6)[/tex]
Therefore the remainder of the quotient:
[tex]f(-6)=14[/tex]
