 Hello and welcome to the session. In this session we will discuss a question which says that draw a graph to represent each situation. First is a card depreciates in value and second is a cup of coffee being waited and then being set on a counter. Now before starting the solution of this question we should know some results. First is, upward movement of graph shows an increase in quantity along y-axis and downward movement of graph decreases in quantity along the y-axis. Now these results will work out as a key idea by solving out the given question. Now let us start with the solution of the given question. Now in this question we have to draw a graph to represent each situation. Now let us draw the graph for the first situation and to graph the depreciating value of card reduces or depreciates a decreasing relationship between value of... Now here on vertical axis we take now here value on time initially the value of card was high but as time increases decreases initially this value decreases at a faster speed and later it decreases slowly to a very long time it will become a chip between value and time and initially value decreases at a higher rate and later it decreases at a slower rate handedly in the curve then we have now here you can see initially the value is decreasing initially at a fastest later after some time it decreases slowly to a long time it is almost which represents the depreciating value of a card. Now let us start with the second part of the graph to represent a being heated and then on a counter. Now here we have to draw the graph showing the relationship between temperature of coffee and time on vertical axis we take temperature on the axis we take now first of all it is given to us that the cup of coffee is heated with time the temperature will increase from key idea we know that an increase in quantity along y axis now in this graph along y axis we have taken the temperature and here initially with time the temperature is increasing we will draw the increase first at a slower pace it will increase at a faster pace in the next part of graph we will draw another line steeper then the previous line so here we have drawn another line which represents that temperature is increasing at a faster pace then temperature reaches its highest point which is shown by this peak and then slowly we put it off it means temperature is reduced now we set it on counter so with time the temperature of coffee will decrease temperature decreases with the fastest we will draw this line and then temperature decreases at a slower pace we will draw another line in the next part of the graph and here line segment AB the line segment half that represents being heated being set on a counter now for representing the same situation if you draw a curve freehandedly then we will get this curve with time but after reaching its highest point it is set on counter its temperature starts decreasing and continues to decrease with time that's the given question that's all for this session hope you all have enjoyed the session
