Derivatives of Polynomial Functions: Power Rule, Product Rule, and Quotient Rule

The video tutorial covers the basics of taking derivatives, starting with the power rule for polynomials. It introduces derivative notation and explains the constant multiple and sum rules. The product and quotient rules are also discussed, with examples provided to illustrate their application. The tutorial emphasizes the importance of understanding these rules for solving calculus problems.

What does the notation d/dx represent in calculus?

• Addition

• Multiplication

• Differentiation

• Integration

According to the power rule, what is the derivative of x^3?

• x^2

• x^3

• 3x^2

• 3x^3

How does the constant multiple rule affect the derivative of a function?

• It adds a constant to the derivative

• It divides the derivative by the constant

• It multiplies the constant by the derivative

• It subtracts a constant from the derivative

What is the derivative of the polynomial 4x^5 + 3x^3 - 2x?

• 20x^4 + 9x^2 - 2

• 5x^4 + 3x^2 - 2

• 20x^5 + 9x^3 - 2

Which rule is used to find the derivative of a product of two functions?

• Sum Rule

• Quotient Rule

• Power Rule

• Product Rule

Using the product rule, what is the derivative of x^2 * 3x?

• 3x^3

• 6x^3

• 6x^2

• 5x^2

What is the correct expression for the quotient rule?

• (f'g - gf')/g^2

• (gf' - fg')/g^2

• (fg' - gf')/g^2

• (f'g - fg')/g^2

In the quotient rule, why is the order of terms important?

• Because it involves a sum
