Question

Identify the number of intervals in the below graph.

  1. 3
  2. 4
  3. 5
  4. 6

hintHint:

In this question we have to find the total number of the interval in given graph. An interval on a graph is section of x-axis is usually examine to see whether the graph is increasing or decreasing in that section.

The correct answer is: 5


    Here the given question we have to find the total number of the intervals.
    Firstly , we have a given graph which distance vs time.
    For interval we have to look the x- axis , along x-axis the graph became discontinued,
    To find interval we mark point on x-axis where the line is discontinued.

    Therefore the line is discontinued on 4 places , and so it has 5 interval on the graph.
    The correct answer is 5 (option (c)).

    In this question, to find intervals we have to find where the graph just discontinued. And as long as graph is continuous and this is interval of this graph.

    John drained the water in his tub. The amount of water left in the tub (in liters) as a function of time (in minutes) is graphed.

    How much water is getting drained in 2.5 minutes?

    In that same question we can also fine the how much amount of water remove at any minutes by finding water drained at one minutes 360/5=72. Which leads to us to find the water drained at any given minutes by multiplying in it.

    How many increasing/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.
