If f(x)=1/2 x-6 what is the equation for f–1(x)?

a. f–1(x) = 2x + 6

b. f–1(x) = 2x – 6

c. f–1(x) = 2(x + 6)

d. f–1(x) = 2(x – 6)

Need on this one asap im almost done with this subject

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?
