What is the derivative function?

• The gradient function of y=f(x)

• The derivative function determines the maximum value of a function
• The derivative function calculates the average value of a function
• The derivative function measures the area under a curve

How is the derivative function labeled?

• f'(x) or dy/dx
• f(x)
• d/dx
• f''(x)

What is a gradient function?

• A function that represents the area under a given function
• A function that represents the average value of a given function
• • A gradient function gives the gradient of the tangent for any given value of x. 

• A function that represents the maximum value of a given function

What is the derivative of f(x)=x²

• 3x
• 2x
• x^2
• x^3

What does the gradient of a tangent do?

• It shows the distance from the origin of the function
• It indicates the color of the function
• For a non-linear function y=f(x),  the gradient of the tangent changes as we move along the curve.

• It measures the temperature of the function
