1. Arrival Activity:
Put the answers to the following question in your notes. Use complete sentences so that you know what your answers mean when you review.
What is average rate of change?
What is instantaneous rate of change?
What equation can we use to find the slope of the secant line?
What is the limit statement that is used to find the slope of a tangent line to a curve?
Are the slope of the tangent line to a curve at x=a and the slope of the curve at x=a the same?

2. Answers Average rate of change is slope between two points.
Instantaneous rate of change is slope a specific moment or single point.
The slope of the secant line can be found using
