ayo jawab no berapun boleh

2) f(x) = 4x - 7
f(-4) = 4(-4) - 7 = - 23
f(-3) = 4(-3) - 7 = - 19
f(-2) = 4(-2) - 7 = - 15
f(-1) = 4(-1) - 7 = - 11
f(0) = 4(0) - 7 = - 7
f(1) = 4(1) - 7 = - 3
f(2) = 4(2) - 7 = 1
f(3) = 4(3) - 7 = 5
f(4) = 4(4) - 7 = 9
himpunan = (-4,-23) (-3,-19) (-2,-15) (-1,-11) (0,-7) (1,-3) (2,1)(3,5)(4,9)
