F(x) = x - 1. Find the inverse of f(x).

f^-1 (x) = x+1

Step-by-step explanation:

f(x) = x-1

y = x-1

Exchange x and y

x = y-1

Solve for y

Add 1 to each side

x+1 = y-1+1

x+1 = y

The inverse is x+1

f^-1 (x) = x+1

If you like shopping, you could say you want to buy x shirts which cost 2$ each and add tax which is $0.75. You have 13$ to make your purchase.

The inequality is:

2x+0.75≤13

-0.75 from both sides

2x≤12.25

divide both sides by two

x≤6.125

This means you can buy 6 or less shirts.
