It is $6$ $6$ .

Explanation:

Just plug $- 1$ $-1$ in for $x$ $x$ in the equation and it gives you the answer

$f (- 1) = - 4 \times (- 1) + 2 = 4 + 2 = 6$ $f(-1)=-4xx(-1)+2=4+2=6$

$f (- 1) = 6$ $f(-1)=6$

Explanation:

$substitute x = - 1 into f (x)$ $"substitute "x=-1" into "f(x)$

$\Rightarrow f (- 1) = (- 4 \times - 1) + 2$ $rArrf(color(red)(-1))=(-4xxcolor(red)(-1))+2$

$\Rightarrow f (- 1) = 4 + 2 = 6$ $color(white)(rArrf(-1))=4+2=6$
