10

Step-by-step explanation:

f(-4) = 2(-(-4) + 1)

f(-4) = 2(5) = 10

Answer 2

Given

$\: \: \:$

• $\tt \: f(x) = - 4$

$\: \: \:$

Let's Solve

$\: \: \:$

• $\tt \: 2( - x + 1)$

$\: \:$

• $\tt \: 2( - ( - 4) + 1)$

$\: \:$

• $\tt \: 2( \: 5 \: )$

$\: \: \:$

• $\tt \color{skyblue} f(x) = 10$
