Question

Suatu fungsi di notasikan sebagai f;x 4-3x dengan daerah asal x { -1,0,1,2,3,4} tentukanlah

Answer 1

F(x)= 4-3x
f(-1)= 4 x (-1x3) = 4 x (-3) = -12
f(0)= 4 x (0x3) = 4 x 0 = 0
f(1)= 4 x (1x3) = 4 x 1 = 4
f(2)= 4 x (2x3) = 4 x 4 = 16
f(3)= 4 x (3x3) = 4 x 9 = 36
f(4)= 4 x (4x3) = 4 x 12 = 48
