Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Let f(x) = 2x, g(x) = x + 5, and h(x) = x^2. Compute h◦(f◦g)(x) and determine if the result matches (h◦f)◦g(x).

💡 Hint: Calculate both sides step by step, evaluating at similar points.

Challenge 2 Hard

Propose a different pair of functions, f and g, and demonstrate that f◦g is not equal to g◦f by providing specific values.

💡 Hint: Choose different simple functions to illustrate this behavior.
