Question

Identify whether the function is increasing, decreasing or constant at the interval pointed in the graph.

  1. Increasing
  2. Decreasing
  3. Constant
  4. Cannot say

hintHint:

In this question we have to find the asked interval is increasing , decreasing or constant. To find the increasing, decreasing and constant we have see the graph and find the slope . If the slope is positive then it is increasing , if slope is negative then it is decreasing and if slope is zero then it is constant.

The correct answer is: Increasing


    Here we have to find the interval is increasing, decreasing or constant.
    Firstly, we have given graph and interval ,

    Now the interval first point is in 3rd quadrant and next point in 1st quadrant ,
    So we can say that interval is moving upward toward left to right.
    And also its slope is positive ,
    Therefore. At that interval the graph is increasing,
    The correct answer is increasing.

    For finding increasing, decreasing and constant interval in any particular interval you must look line whose going downward , upward or horizontal and also find by finding slope of interval .

    Mike, who is a bicyclist is riding along a flat road. He then goes downhill. Can you identify the output variable when you represent the distance traveled over time with a qualitative graph?

    The input variable are change or measured along the horizontal axis or x-axis and the output variable along the vertical axis or y-axis. And here distance on which is dependent variable because it is at y-axis.

    How many increasing and decreasing intervals are there in this 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.

    What is the definition of function?

    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.
