Q: The function f(x) = x^2 + 2x + 1 is differentiable everywhere?
Solution:
f(x) is a polynomial function, which is differentiable everywhere.
Steps: 4
Show Steps
Step 1: Identify the function given, which is f(x) = x^2 + 2x + 1.
Step 2: Recognize that this function is a polynomial because it is made up of terms with x raised to whole number powers.
Step 3: Understand that polynomial functions are smooth and continuous everywhere on the real number line.
Step 4: Conclude that since f(x) is a polynomial, it is differentiable everywhere.
