Question

HELP ME PLEASEEEEEEEEEEEEEEEEE

Answer 1

Answer:

x

Step-by-step explanation:

f($f^{-1}$(x))

Lets work the brackets first!

$f^{-1}$(x)

To solve we are going to find the inverse of the function.

$f^{-1}$(x)

f ⇔ y

∴ y = x

Interchange x and y

x = y

Solve for y

y = x

∴ $f^{-1}$(x) = x

Now let's solve the rest of the equation.

f(x) = x

∴ f($f^{-1}$(x)) = x

Answer 2

The answer is just x
