In simple terms, in the rate of change, the amount of change in one item is divided by the corresponding amount of change in another. Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. Not every function has an absolute maximum or minimum value. Synonyms for Average Rate (other words and phrases for Average Rate). It does not have to be positive or be in a set of whole numbers for a rate of change to be constant. Figure \(\PageIndex{8}\) provides screen images from two different technologies, showing the estimate for the local maximum and minimum. The y-coordinates (output) at the highest and lowest points are called the absolute maximum and absolute minimum, respectively. negative 5 to negative 2 is negative 2. At 75 m.
