Answer:
f(x) and its inverse are the same
Step-by-step explanation:
<u>The inverse function </u>
If y=f(x), the inverse function is defined such as
To find the inverse function, there is a practical method:
a) Change letters x for y and vice-versa
b) Isolate y in terms of x only
c)
In our case,
a) Interchanging letters
b) Isolate
c)
As we can easily see, f and its inverse are exactly the same
