Solution

Your input: find $$$f\left(3\right)$$$ for $$$f\left(x\right)=x^{3} - x^{2} + 2 x + 7$$$.

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

Thus, to find $$$f\left(3\right)$$$, find the remainder from dividing $$$x^{3} - x^{2} + 2 x + 7$$$ by $$$x - 3$$$.

For this, use the synthetic division calculator.

The remainder is $$$31$$$, therefore, $$$f\left(3\right)=31$$$.

Answer: $$$f\left(3\right)=31$$$.
