Answer 1

f(3) = 18...true
f(-3) = 6...true
f(-22) = -56...false
f(-12) = -12...true
f(-1) = 11...false

Answer 2

f(3) = 2*3 + 12 = 6 + 12 = 18  true

f(-3) =  2*(-3) + 12 = -6 + 12 = 6  true

f(-22) = 2*(-22) + 12 = -44 + 12 = -32  false

f(-12) = 2*(-12) + 12 = -24 + 12 = -12  true

f(-1) = 2*(-1) + 12 = -2 + 12 = 10 false
