Question

Davin keeps a record in graph form of how far his car travels and the number of gallons of gasoline it uses. What is the number of gallons that Davin uses per 32 miles?

  1. 1 gallon
  2. 2 gallons
  3. 4 gallons
  4. 8 gallons

hintHint:

Davin keeps record of graph about number of gallons of gasoline used while he was traveling. Here we have to find out the number of gallons in per 32 miles. To find that we have given graph. First find the how much miles its takes for 1 gallon and then multiply it to 32 . This help you to find the solutions.

The correct answer is: 1 gallon


    Here we have to find out the total gallons of gasoline used per 32 miles.
    Firstly , we have given graph, x-axis is gallons of gasoline and y-axis is miles.

    According to graph, it has 3 point ,
    Lets take points be a,b,c
    We can easily tell the coordinate of b is (2,64) , which says that
    The number of gallon used is 2 (it is x-axis coordinate) and miles travels is 64 ,
    So here , for 64 miles its takes 2 gallons of gasoline,
    To find 1 gallon , we have:
    2 gallons = 64 miles
    For 1 gallon we have to divide both side by 2 , we have
    2/2 gallons = 64 /2 miles
    1 gallons = 32 miles
    Therefore , at per 32 miles car used 1 gallon of gasoline.
    The correct answer is 1 gallon (option (a)).
    graph

    To find the solution we have focus on the given coordinate on the graph. It will help you to find the x and y coordinate by that you can easily find the solution. And also find for one thing first and then by that you can easily find given thing. Apply the same concept in similar questions.

    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.

    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.
