Questions & Step-by-Step Solutions

If f(x) = 5x^2 + 3x - 1, what is f'(2)? (2020)
  • Step 1: Identify the function f(x) = 5x^2 + 3x - 1.
  • Step 2: Find the derivative of the function, f'(x). The derivative of 5x^2 is 10x, and the derivative of 3x is 3. The derivative of -1 is 0.
  • Step 3: Combine the derivatives to get f'(x) = 10x + 3.
  • Step 4: Substitute x = 2 into the derivative: f'(2) = 10(2) + 3.
  • Step 5: Calculate 10(2) which equals 20.
  • Step 6: Add 20 and 3 to get 23.
  • Differentiation – Understanding how to find the derivative of a polynomial function.
  • Function Evaluation – Evaluating the derivative at a specific point.
