Question

F(x)= 2x+5 Dengan DA=(-3, <x,<5, x, € B) Tentukan DH

Answer 1

DA = {-2,-1,0,1,2,3,4}


f(x) = 2x+5
maka,
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
f(3) = 2.3+5 = 6+5 = 11
f(4) = 2.4+5 = 8+5 = 13
jadi,
DH = {1,3,5,7,9,11,13}
