Question

Consider the Function

Which function could be the inverse of function f?

Answer 1

Explanation below, despite missing details in question.

Explanation:

The function isn't given but we know it's labelled "f".

The inverse of a function (likewise the inverse of any other quantity) is simply the function turned up-side-down.

To invert a function, you switch the places of both numerator and denominator. Example:

f =
`(x)/(y)`

the inverse of the function above is y/x

If the function is not in fraction form or doesn't have a visible denominator, take the denominator to be 1.

The denominator of every number or function is 1, so you'll be correct doing this.

If f = 2n +5 then the inverse of f will be
`(1)/(2n + 5)`

NOTE: Inverse of f ≡ 1/f ≡
`f^(-1)`
