Question 999123: Each month, Jason wants to save money for a mini IPAD. The mini IPAD costs $300. Jason has $120 and can save $40 a month. The function for this situation can be represented as: S(m) = 40m + 120 where m represents the number of months and S (m) represents the amount of money saved after those months.
f(1)= $160 f(2)= $200 f(3)= $240 f(4)=$280 f(5) = $320
Therefore, after 5 months of saving, Jason has enough to buy the mini IPAD. So, what is the domain and range of this function?

Domain:: {x |0<=x<=5, and x is a Real Number}
------
Range:: { y | 0<= y <=320, and y is a Real Number}
