Answer:
A and C
Step-by-step explanation:
A
when x = 2 , that is x > 1 then f(x) = x² , that is
f(2) = 2² = 4 ← True
B
when x = 5, that is x > 1 then f(x) = x² , that is
f(5) = 5² = 25 ≠ 1 ← not true
C
when x = 1 then f(x) = 5 , that is
f(1) = 5 ← True
D
when x = - 2 , that is x < 1 , then f(x) = 2x , that is
f(- 2) = 2(- 2) = - 4 ≠ 4 ← not true
