Question

How many increasing and decreasing intervals are there in this graph?

  1. 2 increasing, 2 decreasing
  2. 1 increasing, 2 decreasing
  3. 2 increasing, 1 decreasing
  4. 1 increasing, 1 decreasing

hintHint:

It is important to distinguish between increasing and decreasing interval  in graph. The increasing interval means equation having  the slope of the graph is always positive and decreasing interval  means the slope of the graph is negative.

The correct answer is: 2 increasing, 2 decreasing


    Firstly , to find the increasing and decreasing interval in graph we must look the how many increasing line are there and how many decreasing lines are there in graph.
    A function is increasing where the graph gets higher as it moves towards left to right the interval.
    And function is decreasing where graph gets lower as it moves towards left right over the interval.
    graph

    Here we must look the How many times the graph go towards higher and lower from left to right in intervals.

    Fig-2
    According to fig-2 , it has 4 interval,
    In first interval, the graph is decreasing , because the slope of graph is negative.
    In second interval, the graph is increasing , because the slope of graph is positive.
    In third interval, the graph is decreasing, because the slope is negative.
    In fourth interval , the graph is increasing, because the slope is positive.
    Therefore, the graph have 2 increasing interval and 2 decreasing interval .
    The correct answer is 2 increasing and 2 decreasing (option (a)).
    graph

    It very easy to find the increasing and decreasing interval in graph you just have to focus on the graph where its going upward or downward or you can also find increasing and decreasing by finding the slope of the line. If the slope is positive then line is increasing otherwise slope is negative then line is decreasing.

    Let us consider a function that defined as f space colon space X rightwards arrow Y. then, the representation may exist as shown below.
    func-diag (y=sqrt x)
    Hence, Every object x that belongs to the set of inputs has exactly one object y that belongs to the set of outputs.
    *** Hence, the technical definition of the function is a relation from a set of i9nputs to set of possible outputs where each input is related to exactly one output.
