Intervals of Increase and Decrease Date_____ Period____ For each problem, find the x-coordinates of all critical points, find all discontinuities, and find the open intervals where the function is increasing and decreasing. y Increasing & Decreasing Functions and the 1st Derivative Test If the graph shown at the right is a transformation of the parent function , which choice is a possible equation for this function? Example 1: Identify the intervals where the function is increasing, decreasing, or constant. The graph of the constant function f(x) =k is the graph of the equation y = k, which is the horizontal line. is increasing, decreasing, or constant on the given the intervals on increasing in two different intervals and decreasing in one interval. 1: Confidence Intervals ‐allow us to estimate a range of values for the population mean or proportion. Worksheet Math 124 Week 3 2. (3)Sketch a possible graph of a function y = f(x) over the interval [ 2;2] 1 Section 3. To this end, let us begin by taking the first derivative of f(x): To find when a function is increasing, you must first take the derivative, then set it equal to 0, and then find between which zero values the 171S2. 21 2. So f(x) = x2 is decreasing on the interval (1 ;0) and increasing on the A horizontal translation may affect the increasing / decreasing (if multiplied by a negative), the left hand / right hand behavior of the graph, and the y-intercept, but it won't change the location of the horizontal asymptote. 4A.
