Decreasing Graph Definition. If a function is differentiable then it is decreasing at all points where its derivative is negative. A decreasing function has a downward slope over the entire graph.
The average rate of change of an increasing function is positive and the average rate of change of a decreasing function is negative. F is increasing decreasing at a point c if there is an interval ab containing c so that f is increasing decreasing on ab. A function with a graph that moves downward as it is followed from left to right.
For all and all The right hand side represents the straight line between and in the graph of as a function of.
A function with a graph that moves downward as it is followed from left to right. A function with a graph that moves downward as it is followed from left to right. You would know that if something is increasing it is moving upwards and if something is decreasing it is moving downwards. Even though we have not defined these terms mathematically one likely answered that f is increasing when x1 and decreasing when x1.
