6km = 15rb
15km = 25rb
24km = 35rb
ditanya:
60km = ? rb
jawab:
misal 60km = x rb

x = 150
jadi penumpang harus membayar Rp 150.000,- (a)
25] diket:
f(x) = 4x - 1
f(a) = -5
ditanya:
a = ?
jawab:
misal f(x) = 4x - 1 <==> f(a) = 4a - 1
maka
f(a) = f(x)
-5 = 4a - 1
-5 + 1 = 4a
-4 = 4a
-1 = a
jadi nilai a adalah -1 (b)
