Question

Fungsi x= 3x-5 dgn x € [-3,-2,-1,0,1,2] . Daerah hasil f adalah ....??

Answer 1

F(x) = 3x - 5
f(-3) = 3(-3) - 5 = -9 - 5 = -14
f(-2) = 3(-2) - 5 = -6 - 5 = -11
f(-1) = 3(-1) - 5 = -3 - 5 =  - 8
f(0) = 3(0) - 5) = -5
f(1) = 3(1) - 5 = -2
f(2) = 3(2) - 5 = 1
daerah hasil = { -14,-11,-8,-5,-2,1}
