Jawaban:
4. f(x) = 7x + p
f(2) = 10
7 × 2 + p = 10
14 + p = 10
p = 10 - 14
p = -4
f(3) = 7 × 3 + (-4) = 21 - 4 = 17
f(-2) = 7 × (-2) + (-4) = -14 - 4 = -18
5. f(x) =ax + b
f(3) = 11
f(1) = 7
a × 3 + b = 11
a × 1 + b = 7
3a - a = 11 - 7
2a = 4
a = 4 ÷ 2 = 2
3a + b = 11
3 × 2 + b = 11
6 + b = 11
b = 11 - 6
b = 5
