Question

Find the (f of f) (0) f(x)=3x-2

Answer 1

To find (f of f)(0), substitute the value of f(0) into the function and evaluate.

Step-by-step explanation:

To find (f of f)(0), we need to first find f(f(0)). Given that f(x) = 3x - 2, let's substitute f(0) into the function.

1. f(0) = 3(0) - 2 = -2
2. Now, let's substitute this value into the function again:
3. f(f(0)) = f(-2) = 3(-2) - 2 = -8

Therefore, (f of f)(0) is equal to -8.

Answer 2

First write (f o f)(x). This calls for us to use f(x) = 3x-2 as the input to f(x).

f(x) = 3x - 2 => f( ) = 3( ) - 2 Now subst. f(x) inside both sets of parentheses:

f(f(x)) (f o g)(x) = 3(3x-2) -2 = 9x - 6 - 2 = 9x - 8 (answer)
