The cost C of buying g gallons of gas at $2.39 per gallon is C = f(g) = $2.39g a. Find the inverse of this function. Show your work. b. Identify the independent and dependent variables for the inverse function. Independent variable: Dependent variable: c. Calculate −1 (12) and interpret its real world meaning.

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

other answer is correct. i had used the radius of the radius somehow. a website:

-3.5 degrees per hour

step-by-step explanation:

find the unit rate:

-12   1/4 degrees           12.25 degrees

= - = -3.5 degrees per hour

      3   1/2 hours               3.5 hours

simple 80 pieces in 1 sercing so 80*47=3760+20=3780
