Answer:
f^-1(x) = (x -2)/3
Step-by-step explanation:
To find the inverse function, swap x and y, then solve for y.
y = 3x +2 . . . . given function
x = 3y +2 . . . . inverse relation
x -2 = 3y . . . . subtract 2
(x -2)/3 = y . . . divide by 3
f^-1(x) = (x -2)/3 . . . . in functional form
The answer is y=bx-b(a-1), because when x=a then y=b.
What are you asking? Are you asking for the room temperature? Or the oven temperature?
Room temperature=45° F or 50 ° F.
Oven temperature = 90° F to 95° F.
