identify the coordinates of four points such that the slope of the tangent line at that point is: o zero o undefined o positive o negative 2. Evaluate the derivative at the points you identified in step 1. 3. Write a paragraph (5-10 sentences) summarizing the relationship between the continuity of a function, the limit of a function, the slope of a tangent line, and the derivative evaluated at a point. Use your work in Discussions 1-4 to support the conclusion. -5- -10 -5 0 5 10 -5 + N ( x - 2) 2 X ( x - 1 )
