♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

y =f(x) =   - 2x + 4

_________________________________

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

f( - 4) = 8 + 4

f( - 4) = 12

_________________________________

f(0) =  - 2(0) + 4

f(0) = 0 + 4

f(0) = 4

_________________________________

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

f(5) =  - 10 + 4

f(5) =  - 6

_________________________________

Range = { 12 , 4 , -6 }

Thus the correct answer is (( A )) .
