find ( f o f ) ( 0 )

Question

find ( f o f ) ( 0 )

f ( x ) = x^2 - 1

Answer 1

Greetings! Lets solve this shall we ?

So, we must find the composition function f[f(0)] such that

f(x) = x² - 1

f(0) = (0)² - 1

= 0 - 1

= -1

Then we plug in -1 into f(x) such that f(-1) = (-1)² - 1 = 1 - 1 = 0

I hope this helped!
