derp fast Rate of Change (IROC) The exact come out of seduce over of a crop y= f(x) at a special(prenominal) value of the independent inconsistent, x=a; estimated use mediocre rates of change for small musical intervals of the independent variable that ar very close to the value x=a. Exploring Instantaneous rank of Change Using Graphs Key Ideas the slant of the sec cable television service is equivalent to the average rate of change over the intervals delimitate by the X value of two checks that are apply to define the secant cable length. The clear the throat of at tangent at the luff on a graph is equivalent to the fast rate of change of function at this point Need to survive the tip of at tangent cannot be calculated directly using the shift formula because the coordinates of only one point are know the face can be estimated however, by sharp the slopes of a series of secant lines that go through the furbish u p point of Tangent CP and points that get closer and closer to batten point Q1, Q2, and Q3.

As Q approaches P from the left the slope of QP increases and approaches the slope of the tangent line As Q approaches P from the right the slope of QP decreases and approaches the slope of the tangent line. Tangent Line A line that touches the graph at one point, P with in a small interval of a sexual congress; it could only when does not have to bodge the graph at another point outside this interval. The tangent line goes in the same management as the relation at point P (called the point of tangency). [pic] !
