Let $\displaystyle P(x)= 4x^3-5x^2+7x-9$ use synthetic substitution to find $\displaystyle P(2)$

First i use synthetic substitution to get $\displaystyle -7$ for $\displaystyle P(2)$ But according to the table for the equation $\displaystyle 2$ is supposed to equal $\displaystyle 17$ could you explain what I did wrong?
