Consider a function fff satisfying f(x)=∣x3−7x∣f(x) = | x^{3} - 7x |f(x)=∣x3−7x∣. What is the value of f(3)f(3) f(3)?
If fff is a function such that f(f(x))=x2−1 f(f(x)) = x^2 - 1 f(f(x))=x2−1, what is the value of f(f(f(f(3)))) f(f(f(f(3)))) f(f(f(f(3))))?
Consider a function fff satisfying
f(x)=x2.f\big(\sqrt{x}\big)=x^2.f(x)=x2.
What is the value of f(2)?f(2) ? f(2)?
If f(x)=ax+bf\left( x \right) =ax+bf(x)=ax+b, where aaa and bbb are real numbers, and f(f(f(x)))=8x+21f\left( f\left( f\left( x \right) \right) \right) =8x+21f(f(f(x)))=8x+21, what is a+ba+ba+b?
