Step-by-step explanation:
When x = 5 then x > 3 , thus
f(5) = - 1
When x = 3 then x ≤ 3 , thus
f(3) = - 2x + 2 = - 2(3) + 2 = - 6 + 2 = - 4
-----------------------------------------------------------
When x = - 4 then - 4 ≤ x ≤ 1 , thus
f(- 4) = 2
When x = 3 then x > 1 , thus
f(3) = - x + 1 = - 3 + 1 = - 2
