Understanding Derivatives in Calculus

What is the primary purpose of using derivatives in calculus?

• To determine the rate of change of a function

• To find the area under a curve

• To calculate the volume of a solid

• To solve algebraic equations

When applying the Power Rule, what is the first step?

• Add one to the exponent

• Bring down the exponent and multiply it by the variable

• Subtract one from the exponent

• Multiply the exponent by the variable

In the function f(x) = 3x^2 + 1, what is the derivative using the Power Rule?

• 3x^2

• 6x

• 6x + 1

• 3x + 2

What is the Product Rule used for in calculus?

For the functions f(x) = x^3 and g(y) = y^3, what is the derivative using the Product Rule?

• x^3y^3

• 3x^3y^2 + 3x^2y^3

• 3x^2y^3 + 3x^3y^2

• 3x^2 + 3y^2

What is the Quotient Rule formula for finding the derivative of a function f(x)/g(x)?

• (fg' - f'g)/g^2

• (f'g + fg')/g^2

• (f'g - fg')/g^2

• (fg' + f'g)/g^2
