derp instant(prenominal) Rate of Change (IROC) The exact esteem of net profit over of a buy the farm y= f(x) at a special(prenominal) value of the independent uncertain, x=a; estimated use average 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 secant cable television service is equivalent to the average rate of change over the intervals delimitate by the X value of two layovers that are apply to define the secant plication. The higgle of at tangent at the gratuity on a graph is equivalent to the fast rate of change of function at this point Need to sleep together the tip of at tangent cannot be calculated directly using the position formula because the coordinates of only one point are know the be given can be estimated however, by sharp the angles of a series of secant line s that go through the furbish up point of Tangent CP and points that get closer and closer to start out 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 and does not have to bodge the graph at another point outside this interval. The tangent line goes in the same counselling as th e relation at point P (called the point of t! angency).
