Questions & Step-by-Step Solutions

What is the slope of the tangent line to f(x) = x^2 + 2x at x = 1? (2023)
  • Step 1: Identify the function we are working with, which is f(x) = x^2 + 2x.
  • Step 2: Find the derivative of the function, which tells us the slope of the tangent line. The derivative f'(x) is calculated as follows: f'(x) = 2x + 2.
  • Step 3: Substitute the value of x = 1 into the derivative to find the slope at that point. So we calculate f'(1) = 2(1) + 2.
  • Step 4: Perform the calculation: 2(1) + 2 = 2 + 2 = 4.
  • Step 5: Conclude that the slope of the tangent line to the function f(x) at x = 1 is 4.
