we know the 100% is 50 today, by 1863 there were 35, so what is 35 in percentage off 50?
The steps to finding the inverse is writting:
- y = x + 5
- x = y + 5 (applying a change of variables).
- y = x - 5 (isolating y).
Here we have the function:
y = f(x) = x + 5
Basically, to find the inverse we need to isolate x. The first step is writing
y = x + 5
Now let's do a <em>"false change of variables"</em> of x by y, so we get:
x = y + 5
Now we need to isolate y again:
y = x - 5
This is the inverse of the function f(x), we have:
