Solution

Your input: find f(3) for f(x)=x3x2+2x+7.

According to the remainder theorem, f(a) is the remainder from dividing f(x) by xa.

Thus, to find f(3), find the remainder from dividing x3x2+2x+7 by x3.

For this, use the synthetic division calculator.

The remainder is 31, therefore, f(3)=31.

Answer: f(3)=31.
