Answers
Given : a videoke machine can be rented for 1000 for three days but for the fourth day onward an additional cast Php 40 per day s added
To Find : represent the cost of renting a videoke machine as a piecewise function of the number of days renting
Solution:
d = number of days
f(d) = cost
videoke machine can be rented for 1000 for three days
Rented Days can not be Negative or zero
f(d) = 1000 0 < d ≤ 3
for the fourth day onward an additional cast Php 40 per day
=> f(d) = 1000 + 40(d-3) 3 < d
=> f(d) = 1000 + 40d - 120 3 < d
=> f(d) = 4d + 880 3 < d
Piece wise function
f(d) = 1000 0 < d ≤ 3
4d + 880 3 < d
