diketahui notasi fungsi f:x -> 5x+4. daerah asal= {-2,-1,0,1,2}. daerah hasil fungsi tersebut adalah...

f(x) = 5x+4
D={-2,-1,0,1,2}
f(-2) = 5(-2)+4 = -6
f(-1) = 5(-1)+4 = -1
f(0) = 5(0)+4 = 4
f(1) = 5(1)+4 = 9
f(2) = 5(2)+4 = 14
R={-6,-1,4,9,14}

5(-2)+4 = -6
5(-1)+4 = -1
5(0) +4 = 4
5(1) + 4 = 9
5(2) + 4 = 14
daerah hasil fungsi {-6, -1, 4, 9, 14}
