Answer:
j
Step-by-step explanation:
Substitute the given values into x² + x + 1 and check if result is prime
x = - 4
(- 4)² - 4 + 1 = 16 - 4 + 1 = 13 ← prime
(- 2)² - 2 + 1 = 4 - 2 + 1 = 3 ← prime
(- 3)² - 3 + 1 = 9 - 3 + 1 = 7 ← prime
4² + 4 + 1 = 16 + 4 + 1 = 21 ← not prime
x = 4 serves as a counterexample to disprove this conclusion

Answer:
Hello your question is incomplete below is the complete question
option B is correct
f(x) = 1 if x ≤ 0
-2 if x > 0
Step-by-step explanation:
The Rule of the piece-wise-defined function is :
from the given figure attached it can be seen that as : x ≤ 0 , y = 1
while for x > 0 , y = -2
therefore option B is correct
f(x) = 1 if x ≤ 0
-2 if x > 0
