The product of -2 and a number minus 6 is greater than -18

So product means multiplication so -2*(x-6) > -18 so divide by -2 on both sides to get x-6<9 because when you multiply a negative the sign swaps directions and then add 6 to get x<15

Which Of the following pairs of functions are inverse of each other?
damaskus [11]

One way is to solve for the inverse of the first function

remember, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with f^{-1} (x)

A.

f(x)=x/2+8\\y=x/2+8\\x=y/2+8\\x-8=y/2

2x-16=y

f^{-1}=2x-16

nope, not A

<h3>What is the inverse function?</h3>

The inverse function of a function f is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by {\displaystyle f^{-1}.}

B.

f(x)=3x^3+16\\y=3x^3+16x=3y^3+16\\x-16=3y^3\\(x-16)/3=y^3

f^{-1}(x)=\sqrt[3]{((x-16)/3)}

nope, not the same

not B

C.

f(x)=18/x-9\\y=18/x-9\\x=18/y-9\\x+9=18/y\\y(x+9)=18\\y=18/(x+9)\\f^{-1}(x)=18/(x+9)

The correct, answer is C.
