F(C) = 95C + 32...
F(C) is y.
y = 95C + 32
Switch Y & C.
C = 95y + 32
C - 32 = 95y
(C - 32) / 95 = y
In the inverse, y is F-1(C)

F-1(C) = (C - 32) / 95

Answer:


f^(-1)(C)=(5)/(9)(C-32)

Explanation:

Given : Function
F(C)=(9)/(5)C+32

We have to find the inverse of the give function.

Inverse is calculated by putting function f (x) = y ,now taking inverse of f both side , we have,
f^(-1)(y)=x and then finding value of x in terms of x. We obtain inverse of function.

Let
F(C)=(9)/(5)C+32

Put F(C) = y ,

then
f^(-1)(y)=C ...........(1)


y=(9)/(5)C+32

Subtract 32 both sides, we have,


y-32=(9)/(5)C

Now multiply both side by
(5)/(9) , we have,


(5)/(9)(y-32)=C ......(2)

From (1) and (2) , we have,


f^(-1)(y)=(5)/(9)(y-32)

Replace y by C, we have,


f^(-1)(C)=(5)/(9)(C-32)
