Question

K{-2,-1,0,1,2} fungsi f:x ditentukan oleh f(x)=3x-2.tentukan daerah hasil Dari f

Answer 1

Verified answer

F(x) = 3x - 2
daerah asal = {-2,-1,0,1,2}

f(-2) = 3(-2)-2 = -6-2 = -8
f(-1) = 3(-1)-2 = -3-2 = -5
f(0) = 3(0)-2 = 0-2 = -2
f(1) = 3(1)-2 = 3-2 = 1
f(2) = 3(2)-2 = 6-2 = 4

daerah hasil = { -8,-5,-2,1,4}
