Consider the function given by f(x) = en/2-earctan (1+x²). (Note: arctan (1 + x²) is the power to which e is being raised.) This function has derivatives: 2xearctan(1+x²) f'(x) 2(3x4-2) earctan (1+x²) ((x² + 1)² + 1)² (x² + 1)² +1' 1. (4 points) What is the domain of f? (Give your answer in simplified interval notation). == 2. (4 points) Build a sign chart for f'(x). 3. (6 points) Build a sign chart for f"(x). f"(x) =
