Questions & Step-by-Step Solutions

If f(x) = e^x, what is f''(0)?
  • Step 1: Identify the function given in the question, which is f(x) = e^x.
  • Step 2: Find the first derivative of the function, f'(x). The derivative of e^x is e^x, so f'(x) = e^x.
  • Step 3: Find the second derivative of the function, f''(x). The derivative of e^x is still e^x, so f''(x) = e^x.
  • Step 4: Evaluate the second derivative at x = 0. Substitute 0 into f''(x): f''(0) = e^0.
  • Step 5: Calculate e^0. The value of e^0 is 1.
  • Step 6: Conclude that f''(0) = 1.
  • Differentiation – The question tests the understanding of how to differentiate the exponential function and evaluate the second derivative at a specific point.
  • Exponential Function Properties – It assesses knowledge of the properties of the exponential function, particularly that the derivative of e^x is e^x.
