Answer:

B

Explanation:

So we have the function:


f(x)=(9)/(5)x+32

To find the inverse, flip f(x) and x, change f(x) to f⁻¹(x), and solve for it. Thus:


x=(9)/(5)f^(-1)(x)+32

Subtract 32 from both sides:


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

Multiply both sides by 5/9. The right side will cancel. Thus:


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

Our answer is B.

And we're done!
