Use a recursive function for the geometric sequence 2, −8, 32, −128, … to represent the 9th term. f(9) = f(1) + −4(8)
f(9) = f(8) + −4(8)
f(9) = f(1) • (−4)^8
f(9) = f(8) • (−4)

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?
