........

23.
f(x) ax+b
f(1)= a+b = 4
f(3) = 3a+b = 14
——————––— -
. -2a = -10
a = 5


f (1) = 5 + b = 4
b = 4 - 5
b = -1

jadi, jawabannya C, yaitu 5x-1

24.
3 = -1 berarti 3 - 4 = -1
4 = 1 berarti 4 - 3 = 1
5 = 3 berarti 5-2 = 3
6 =.... hasilnya 6 -1 = 5
7 =.... hasilnya 7-0 = 7
8 =.... hasilnya 8-(-1) = 9
9 =.... hasilnya 9-(-2) = 11
10=.... hasilnya 10-(-3) = 13
