Take out a paper and pencil (and eraser) It is now your turn The graph of f(x) = c is the horizontal line y = c, which has slope 0. examples: The derivative of a constant is zero (Pascals Triangle) We observe a pattern: power rule examples: example: example: examples: Inverse: Example: Remember where we started: Repeating this procedure at several points, we get the graph shown in this figure. Tangents at x = A, B, and C are horizontal. So, the derivative is 0 there and the graph of f crosses the x-axis at those points. Between A and B, the tangents have positive slope. So, f(x) is positive there. Between B and C, and the tangents have negative slope. So, f(x) is negative there. Derivative of a function at a point gives The slope of the tangent line at that point The instantaneous rate of change at that point Application of the Derivative to Motion Then: HOMEWORK 2
