Answer 1

1)
h(x) = 8x + 5
a)
h(x+1) = 8(x+1) + 5
h(x+1) = 8x + 13
perubahannya = 8x + 13 - (8x+5) = 13-5 = 8
.
b) (hx+4) = 8(x+4) +5
h(x) = 8x + 45
perubahan = 8x + 32 - 8x - 5 = 32-5 = 27 
.
2)
h(x) = 9 - 4x
h(x+2) = 9 - 4(x+2)  = 1 - 4x
perubahan = (1- 4x) - (9-4x) = 2-9 = -7
.
h(x+4) = 9 - 4(x+4) = 5 - 4x
perubahan = (5-4x) -(9 -4x) = 5-9 = -4
