untuk fungsi f(x)=2x+5, dengan daerah asal A:{-2,-1,0,1,2}. Bayangan setiap anggota A adalah...

f(-2) = 2(-2) + 5 = -4 + 5 = 1
f(-1) = 2(-1) + 5 = -2 + 5 = 3
f(0) = 2(0) + 5 = 0 + 5 = 5
f(1) = 2(1) + 5 = 2 + 5 = 7
f(2) = 2(2) + 5 = 4 + 5 = 9
Semoga dapat membantu~

f(x) = 2x+5
f(-2) = 2(-2)+5 = -4+5 = 1
f(-1) = 2(-1)+5 = -2+5 = 3
f(0) = 2(0)+5 = 0+5 = 5
f(1) = 2(1)+5 = 2+5= 7
f(2) = 2(2)+5 = 4+5 = 9
