I have the following function $$f(x) = 3x^3 - 5x^2 - 4x + 4.$$

I would like to find the value of $f(x)$ when $x = -3$.

I have ordered the equation in the following way. $$f(-3) = (3 \times -3^3) - (5 \times -3^2) - (4 \times -3) + 4 = -28.$$

Can anyone tell me if the following syntax is correct and if not, where have I gone wrong.

Many Thanks.

    Is your function supposed to be $f(x) = 3x^3 -5x^2-4x+4$?2011-02-23

    You wrote $f(x)=3x^2-...$ (squared, not cubed). That's why I asked.2011-02-23
