Question

Evaluate the expression: \[ f\left(f(f(x))\right) + \left(f(f(x))\right)^2 \quad \text{if} \quad x = 1 \]

• A. \( f(f(f(1))) + \left(f(f(1))\right)^2 \)
• B. \( f(f(f(1))) + \left(f(1)\right)^2 \)
• C. \( f(1)^2 + f(1) \)
• D. Cannot be determined

Hint:

Always ensure the function \( f(x) \) is provided before attempting to evaluate composite or nested functions. Without definition, expressions involving \( f(x) \) cannot be simplified.

Answer 1

The Correct Option is D

To evaluate the expression \[ f\left(f(f(x))\right) + \left(f(f(x))\right)^2 \quad \text{at} \quad x = 1, \] we need to know the explicit form of the function \( f(x) \). Since the function is not defined in the problem statement, the expression cannot be evaluated numerically.
