Answer
$v(-3)=23$
$v(0)=14$
$v(4)=2$
Work Step by Step
The given function is
$\Rightarrow v(x)=14-3x$
Substitute $x=-3$.
$\Rightarrow v(-3)=14-3(-3)$
Simplify.
$\Rightarrow v(-3)=14+9$
$\Rightarrow v(-3)=23$
Substitute $x=0$.
$\Rightarrow v(0)=14-3(0)$
Simplify.
$\Rightarrow v(0)=14-0$
$\Rightarrow v(0)=14$
Substitute $x=4$.
$\Rightarrow v(4)=14-3(4)$
Simplify.
$\Rightarrow v(4)=14-12$
$\Rightarrow v(4)=2$
