If $f(x) = 2x^3 - 13x^2 + 17x + 12$, find$f(-3)$
Given:
$f(x) = 2x^3 - 13x^2 + 17x + 12$
To do:
We have to find $f(-3)$.
Solution:
To find $f(-3)$ we have to substitute $x=-3$ in $f(x)$.
Therefore,
$f(-3) = 2(-3)^3 - 13(-3)^2 + 17(-3) + 12$
$= 2 (-27)-13 (9)+(-51)+12$
$= -54-117 -51 + 12$
$= 12 - 222$
$= -210$
Hence, $f(-3) = -210$.
