- What is the formal definition of a derivative?
- What does the derivative of a function tell you?
- How can you find the slope of a tangent line to a curve at a point on a curve?
- How do you find the derivative of a line?
- If f(x) = 3x - 2, what is f'(x)?
- How can you find the derivative of f(x) = 3x - 2 using the formal definition of a derivative?
- What is the derivative of f(x) = mx + b?
- If f(x) = 2 - x^2, how do you find f'(x) using the formal limit definition of a derivative?
- What is the slope of the tangent line to f(x) = 2 - x^2 at (0, 2) and (2, -2)?
In this lesson, you will learn to find the derivative of a line using the formal limit definition of a derivative. There is one more example of finding the derivative of a quadratic equation as well. All steps are explained very well as they are in the whole series.
