Diketahu fungsi f(x) = 2x - 5 Daerah asal D = {-2, -1, 0, 1, 2} Tentukan daerah hasilnya

f(-2)= 2.(-2) - 5 = -9
f(-1)= 2.(-1) - 5 = -7
f(0)= 2.0 - 5 = -5
f(1)= 2.1 - 5 = -3
f(2)= 2.2 - 5 = -1

daerah hasil (-9,-7,-5,-3,-1)

f(-2)= 2(-2) -5= -4-5= -9
f(-1)= 2(-1) -5= -2-5= -7
f(0)= 2(0) -5 = 0-5 = -5
f(1)= 2(1)-5= 2-5 = -3
f(2)= 2(2)-5 = 4-5= -1
{-9, -7, -5, -3, -1}
semoga membantu
