hram777 [196]
There are 9 long distance male runners and 5 long distance female runners. This makes a total of 9+5 = 14 long distance runners.

Out of this total of 14 long distance runners, there are 9 males. So the probability as a fraction is 9/14

If you need the answer in decimal form, then use a calculator to get 9/14 = 0.642857 which is approximate.

Given f (x) = 1/4x-3/4<br> Find f^-1
Snowcat [4.5K]

The inverse of a function f(x) is f⁻¹(x) = 4x + 3 after using the concept of the inverse of a function.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

\rm f(x) = \dfrac{1}{4}x-\dfrac{3}{4}

To find the inverse of a function:

Interchange the f(x) and x

f(x) → x

x → f⁻¹(x)

\rm x = \dfrac{1}{4}f^{-1}(x)-\dfrac{3}{4}

Make the subject f(x);

\rm \dfrac{1}{4}f^-^1(x)=x+\dfrac{3}{4}

\rm f^-^1(x)=4x+3

Thus, the inverse of a function f(x) is f⁻¹(x) = 4x + 3 after using the concept of the inverse of a function.
