WebStep 1: Let's try to identify where the function is increasing, decreasing, or constant in one sweep. Take a pencil or a pen. Find the leftmost point on the graph. Then, trace the graph line. If ... WebExample: f(x) = x 3 −4x, for x in the interval [−1,2]. Let us plot it, including the interval [−1,2]: Starting from −1 (the beginning of the interval [−1,2]):. at x = −1 the function is decreasing, it continues to decrease until about … WebUsing a Graph to Determine Where a Function is Increasing, Decreasing, or Constant. As part of exploring how functions change, we can identify intervals over which the function is changing in specific ways. We say that a function is increasing on an interval if the function values increase as the input values increase within that interval. bunk buddy or carpet
