Questions & Step-by-Step Solutions

If f(x) = x^4 - 4x^3 + 6x^2 - 4x + 1, find f'(2).
  • Step 1: Identify the function f(x) = x^4 - 4x^3 + 6x^2 - 4x + 1.
  • Step 2: Find the derivative of the function, f'(x).
  • Step 3: Use the power rule to differentiate each term: The derivative of x^n is n*x^(n-1).
  • Step 4: Differentiate each term: 4x^3 (from x^4), -12x^2 (from -4x^3), 12x (from 6x^2), and -4 (from -4x).
  • Step 5: Combine the derivatives to get f'(x) = 4x^3 - 12x^2 + 12x - 4.
  • Step 6: Substitute x = 2 into the derivative: f'(2) = 4(2)^3 - 12(2)^2 + 12(2) - 4.
  • Step 7: Calculate each term: 4(8) = 32, -12(4) = -48, 12(2) = 24, and -4 remains -4.
  • Step 8: Combine the results: 32 - 48 + 24 - 4 = 0.
  • Step 9: Conclude that f'(2) = 0.
