Unit 3 part II differentiation + 4.1-4.3 particle motion

What is the derivative of a function?

• The derivative is the area under the curve of the function.

• The derivative of a function at a point is the slope of the tangent line to the graph of the function at that point.

• The derivative measures the total distance traveled by the function.

• The derivative is the maximum value of the function.

What is the relationship between the derivative and the slope of a curve?

• The derivative at a point gives the slope of the tangent line to the curve at that point, indicating how steep the curve is at that location.

• The derivative measures the area under the curve at a given point.

• The derivative is the average slope of the curve over an interval.

• The derivative indicates the maximum height of the curve at a specific point.

What is the slope of the tangent line?

• The slope of the tangent line is the second derivative of the function.

• The slope of the tangent line is given by the integral of the function.

• The slope of the tangent line at a point on a curve is given by the derivative of the function at that point.

• The slope of the tangent line is the average rate of change of the function over an interval.
