The inverse is y = x/2 - 4
Steps involved are -
- replace f(x) with y: y = 2(x + 4)
- Then switch y and x: x = 2(y + 4)
- Finally make y the subject:
- x = 2(y + 4)
- x/2 = y + 4 (divide by 2)
- x/2 - 4 = y (subtract 4)
- So, the inverse is y = x/2 - 4
<h3>What is the formula for inverse function?</h3>
- In mathematics, the inverse function of a function f (also called the inverse of f) is a function that undoes the operation of f.
- The inverse of f exists if and only if f is bijective.
- f-1(y) = y/2 = x, is the inverse of f(x).

You have to find the least common variable, and that would be 10. multiply 2/10 by 10 to get 20/100. 4/100+20/100=24/100. it's C
First we need to calculate how many years her brother has when she is 18. As text says he is:
18/3 = 6 years old
Now when she gains another 18 years (36-18=18) he will also gain those 18 years
When she is 36 he will have 6+18=24 years old
Answer is 24.
