Step-by-step explanation:
f(x) = 5x – 1
To find the inverse equate f(x) to y
That's
f(x) = y
y = 5x - 1
Interchange the terms
x = 5y - 1
Make y the subject
we have
5y = x + 1
Divide both sides by 5
y = x+1/5
Therefore f^-1(x)= x + 1/5

Hello there,
If she has 10 books and she can arrange it 3 ways on her bookshelf, you just multiply 10 and 3
