a) h(x) = 4x + 5 = 29
4x = 29 - 5
4x = 24
x = 24 : 4
n = 6
b) h(x) = 4x + 5 = 3
4x = 3 - 5
4x = -2
x = - 1/2
a) f(3) = 2.3 = 6
f(2) = 2.2 = 4
f(1) = 2.1 = 2
f(0) = 2.0 = 0
b) f(x) = 2x
128 = 2x
x = 128 ÷ 2 = 64
2a) h(n) = 4n+ 5
29 = 4n + 5
4n = 29 - 5
4n = 24
n = 24 ÷ 4 = 6
h(n) = 4n + 5
3 = 4n + 5
4n = 3 - 5
4n = -2
n = - 2/4 = -½
3) g(x) = ¼(x + 3)
a) g(0) = ¼(0 + 3) = ¾
g(5) = ¼(5 + 3) = ¼ × 8 = 2
b) g(x) = ¼(x + 3)
7 = ¼(x + 3)
7 × 4 = x + 3
28 = x + 3
x = 28 - 3 = 25
