WebDec 12, 2014 · Most calculus books will define an interval of increase as follows: In other words, bigger x’s give bigger y’s. But, in the case of the quadratic above, wouldn’t the interval: fit this definition? Remember, the question is not whether the function is increasing at x=4. It is whether x=4 is part of an interval where bigger x’s give ... WebTranscript. Finding intervals of increase and decrease of a function can be done using either a graph of the function or its derivative. These intervals of increase and decrease are important in finding critical points, and are also a key part of defining relative maxima and minima and inflection points.
